angles of attack.


The alien forces known as the Lankies are gathering on the solar system’s edge, consolidating their conquest of Mars and setting their sights on Earth. The far-off colony of New Svalbard, cut off from the rest of the galaxy by the Lanky blockade, teeters on the verge of starvation and collapse. The forces of the two Earth alliances have won minor skirmishes but are in danger of losing the war. For battle-weary staff sergeant Andrew Grayson and the ragged forces of the North American Commonwealth, the fight for survival is entering a catastrophic new phase.

Forging an uneasy alliance with their Sino-Russian enemies, the NAC launches a hybrid task force on a long shot: a stealth mission to breach the Lanky blockade and reestablish supply lines with Earth. Plunging into combat against a merciless alien species that outguns, outmaneuvers, and outfights them at every turn, Andrew and his fellow troopers could end up cornered on their home turf, with no way out and no hope for reinforcement. And this time, the struggle for humanity’s future can only end in either victory or annihilation.

ANGLES OF ATTACK was released on April 21, 2015. You can order the book in Kindle, paperback, or audio formats here.


      1. thank you Mr. Kloos! PLEASE keep writing these things as long as your brain allows! I think I speak for many out in the world when I say your books are the best thing in sci-fi right now! HUGE fan here in Manhattan, NYC! Hope the series goes to 20!

  1. I just read both your books, and your story is one of my favorites in science fiction right now. I cant wait to read your next book. Have you any other series in mind in the future besides this one?

  2. I eagerly await the release of Angles of Attack I have gone back and re-read the two previous novels and both of the short stories – several times. I was particularly pleased to see the slight re-write of Terms of Enlistment that fleshed out some things, in particular the small edits and additional story that made the ending seem less rushed.

    The military technology described is quite plausible, the weapons systems are in many ways not that far off from what is being fielded today or on the drawing boards. Drop ships – a little less so but no reason to doubt as a future technology. Even the FTL drive is reasonable in terms of science. Overall, just enough technology is explained to keep the story moving, without wandering off into a geek fest.

    One thing however, keeps sticking in my mind as I read the stories, and that is in regard to the overall cultural and society. While the idea of the two primary power blocks and an overloaded Earth is entirely reasonable and believable, down to the end of welfare blocks and rationed food (something that Jerry Pournelle explored in his Co-dominium future history series).

    But when it comes to the military, it gets just a tad sticky. The ‘terms of enlistment’ are quite clear, pay is retained and distributed AFTER service has been completed….but…. What the hell do the troops do for money? Yes they can eat in government facilities when traveling or on leave, but no pocket money at all? How do the troops buy a few trinkets, negotiate places where government dining halls aren’t available? What about married troops – the story makes it clear there are married troops in Terms of Enlistment, and again in Lines of Departure. So how do the troops buy the kids clothes, etc?

    Just a nitpick in what is a very fine series of hard science fiction, excellent in detail and a coherent society and culture….except that one little detail. It would be nice perhaps to have a ‘companion’ book, even a short story that explains the back story of how the SRA and NAC came about, etc.

    Good work and keep the series going – otherwise your loyal readers might go all “Misery’ on you……………..that was a ‘joke’, cue humor font.

  3. I’m traveling to Taiwan and downloaded TERMS OF ENLISTMENT prior to my flight from the U.S. I was engrossed from the beginning. Imagine my excitement when I finished it and Amazon immediately offered LINES OF DEPARTURE for download. “Sweet!” I thought. A military SF series I finally like. Two weeks into my trip, and I just completed your second book in the series. To my utter disappointment, I couldn’t download the third book. Just did a quick search and found your blog and now I have to say I can’t wait to get ANGLES OF ATTACK. I fly back from Taiwan on April 21st. Please, please, please, let the book be available for download before my flight — I’m worried because I’m at least 12 hours ahead of any part of the U.S. Here’s hoping that Amazon distributes it on time for the international audience. Thanks for starting such a great series!

  4. Marko, like this series very much! One minor, minor thing bothered me a little and that was the anti-Lanky small arms. I was thinking some kind of man-portable anti-armor weapon. I guess I’m really torqued about only two shots! What a small thing in your great MilSf books! My wife says I’m nuts and should take the garbage out. Thanks for the stories!


  5. Just finished my paper copy of Angles of Attack at 4 am in the morning. Yep I had to stay up at all hours to finish it off and thoroughly enjoyed it. The political issues reminded me of the backdrop to the Jerry Pournelle Mercenary series. Quite different but a similar flavour. Perhaps after the 4th book you could consider more in the same Universe

  6. Listening to the audible now, and I must say, of all the amazing SciFi I have found and even Urban Fantasy I have found Luke Daniels has to be one of my ALL time favorite narrators. There are others that are good even great but so far the only thing I have found better are full cast productions. I tried to read the book prior to the audible release and decided to just wait for Luke to do it right. This series is at the top of my list which has 5-8 series doggedly duking it out for the lead. I am not a huge fan of short stories typically and I know that there are some shorts in this series. I wanted to suggest doing what was done with the Koban series and do an audio book of shorts that is in the same universe, but deals with smaller stories that may not have much of an impact on the story as a whole but could be referenced. I found that it added a lot of depth to the universe and the tie in’s were that much more colorful having had read the short stories, however, not needed to understand the situation. I will rabidly be waiting for book four while I also wait for 5-8 other equals some of them in the 4-5 range one of them in the 13th book. Some of them have been released in print but most of them having amazing narrations are just simply worth the wait. Now to go back and review WHY they had there mutiny back in book 2 its been so long! Mostly because I have digested some 130 books since book 2 HAHA!


  7. For some reason “Angles of Attack” does not have a listing on Google Books. The previous two in the series appear on Is there a reason this one is missing? I don’t think the book needs to be in the Play store to appear, it just needs to have been published.

  8. I finished the first two books and have started the third, stopped to search and found this site. Thank You! It has been some time since I have read/listened to any “military-fiction” that has moved me. I served in two Branch’s of the U.S. Military for 34 years, You made an “old war dog/jarhead” smile!

  9. Your story telling is AWESOME! Would you be open to mentoring and guiding a new Sci Fi writer with his first story?

  10. Your books are amazing! The Frontline series has swept me up and really gotten me interested in SF. I was never a SF fan… until Frontlines! Your character development is amazing! Your insight into future technology is genius. I can really “see” this reality in the future and not have the “yeah right,..that will never happen” attitude. Also, Luke Daniels did a FANTASTIC job narrating your books. I think he captured the attitudes and personalities of the story perfectly. Its like three AWESOME movies I get to listen to over…and over… and over. Starting the series over for the third time. I don’t re-read books…ever. And I’ve never read a book that I’ve listened to the audiobook first until this series! So that says something! Keep up the good work, and I cant wait for more Frontlines! I hope you can get 10 books out of this series! Wish you the best of luck and all the future success in the world!

  11. I’m halfway through “Angles of attack” now. Pardon me for the coarse language but SF military BS has always seem a guilty pleasure for me. Unfortunately a lot of it is really really bad. In the genre yours has been pretty good show, fairly authentic military rules nonsense up to the point when the guys go all Robin Hood but still the system tries to stab them in the back even when all us practically lost in Götterdämmerung.

    And now cows the “however” part. Several times in Angles of attack you state that the rail guns do *so* much damage point blank. You should be spanked. Outside atmosphere the rail gun pellet makes exactly the same amount of damage 10m or 100km away. Of course in the latter case actually hitting something is completely different story, never mind ten thousand km away. But the destructive potential is exactly the same or within neglible fraction so. Tsk tsk Mr Kloos but this kind of thing eats at the suspension of disbelief. Not to mention simply saying “you can get perfect hit angle at pinpoint accuracy point blank” while 1000km away you’re lucky to hit anything at all conveys the same story.

    The second bit is that the nasty aliens are just silly. In original D&D game giant ants are chaotic. Why? Well, authors said it’s because of they ignore the law of mass equals volume squared or was it tripled. Lankies are just too damn big, it’s silly. You could shrink them from 30m to 5-10m elephant size and they’d still be a terror.

    Still, this kind of complaints just should show you I really like the content in general terms. Given something groan-some performances in the military BS genre getting down to this kind of detail should real you you’re doing pretty damn ok. Especially as you’re not glorifying fascism like one author credited for power armor we could mention..

    Looking forward to 4th installment. Please do not go time travel mad like one of the other guys within the genre..

      1. Well, yes. Those guys were hardly “surprisingly” fast-moving agile creatures like the Lankies are depicted. In AoA a lanky actually does start climbing up a habitat, which implies pretty respectable mobility for something that massive.

        In a few places lankies are 100 feet and later on 20 meters. but that does not make that much difference.

        Now that I finished AoA, I have the same feeling as before. When are our protagonists going to figure out that “kinetic energy = doubleplus good”? There has been only so many successfull attacks on Lanky ships ever and they’re always been by accelerating a starship to 50km/s plus for much “ouch” on e=mc^2 basis.
        Someone, somewhere, should go “hey wait a minute..”

        As I said before, I really like Mr Kloos books compared to most other contenders in the genre. Scalzi has pretty good stuff and there are others older classics such as “Forever war” or Xeelee-series but mostly it’s just really lousy.

  12. Along the way I’ve started thinking it’s not Lankies and their ships, it’s the ships and their creatures..

  13. I like how you didn’t go into the math, but correctly calculated that the trip time for the Red Route would be twice a long with a 1g acceleration and no stops compared to a 4g acceleration with a stop in the middle. I assume that you also checked that time dilation from 4g acceleration for about 4 days would be insignificant (it is insignificant).

    1. I also like how you correctly calculated that the energy required to accelerate/decelerate at 4gs to the midway point in the Red Route is equal to the energy to accelerate/decelerate at 1 g for the entire trip.

  14. Loving this series! Bought them all in audiobook form. Great storyline, well written and done by one of the best narrators in the business! Very well done! Listening to the end of Angles of Attack right now and have Chains of Command downloaded and ready to play as soon as this is done. Great job Mr. Kloos and congrats on all the accolades. They’re well deserved as far as I’m concerned. One thing I’d love to see is some art to grasp your vision of the Lankys and their ships as well as the battle armor, armaments, and ships of the human forces. Keep up your hard work. I’d love to continue to read your stories for years to come!

  15. I have enjoyed all of the books in the series. I just finished Fields of Fire and I loved it. The series captured my attention and each book has been fantastic! I absolutely hope you will be writing another book in the series. I am a fan of your sci-fi stories of Andrew and Halley. Along with Earth ‘s fight to survive their battles against the Lankies. Keep writing please.


  16. Mr.Kloos.
    I saw you last year at Manticon but have not read your books yet. I was still in the middle of the Honor Harrington Series. i just listened up to Angles of Attack. I am now a huge fan of Frontline. I can’t wait to see you at Manticon this year.
    Thanks for making a 2 hour commute pleasant.

  17. Hello, Marko. I am busy ripping through “Angles” and am enjoying the series a lot. I don’t remember how I stumbled across “Terms” (probably a freeby or $0.99 on BookBub) but about half way through I hit Amazon and picked up the other 4.

    I have to comment you on your depiction of military procedures and dialog. You must have spent time in uniform – likely with stripes on your sleeves – because I have never read anybody’s work that captures the feeling of being in the Armed Forces any better than you have.

    Keep up the good work, young man. Keep up the good work.

    1. Erk! In the 2nd paragraph I MEANT to type “compliment” rather than “comment”. Wish your comments section had an “edit” function.
