A cursory view of your site did not reveal a release date for a follow-on novel. I enjoyed “Terms….” and look forward to reading your next effort.

Looking forward to the next novel! Great stuff! The editing was also outstanding. The one and only issue I found is towards the end of the novel there is a sentence by Halley, @”It’s either that, or putting down in the sticks.” That should be “in the styx.”

Not to pick a fight over editing someone else’s novel on that author’s blog, but…

The only way “in the styx” would make sense in common English would be if it were written “in the Styx”, (note the capitalization–necessary for a proper noun, indicated by ‘the’ and assumption that there’s a specific place-name Styx fits) and that the proposed landing-spot were a river separating us from Hades.

“In the sticks” is fairly common vernacular for a location away from civilization (see: “in the boonies”, “in BFE”, etc)

Very much enjoyed Terms of Enlistment and am looking forward to the sequel(s) (hint hint). As a former native to the wilds of NH, I’m glad to see someone move there with the same ideals as the state motto: “live free or die.”

Could you post a link on your new Blog to your excellent article “Why the Gun is Civilization”? Also since you are now published and have an agent, could you provide your reproduction rights for this work?

    Tam · June 6, 2013 at 5:01 pm

    You’ll need to ask Maj. Caudill about that. 😀

Gaston · June 6, 2013 at 10:56 pm

CPT Tuttle already did.

ZOMG you should publish your twitter feed. You’re a funny man Marko

cbb · April 24, 2014 at 8:41 pm

btw, really, really enjoy your writing. Read Terms and Lines, and whatever else I could find. Just found a short about faeries, quite nice. Your writing reminds me very much of Scalzi (who, I think, is among the best in that sub-genre ever, far better than Heinlein)..keep writing! I’ll keep buying! 🙂

cbb · April 24, 2014 at 11:52 pm

sry, realized prior quick post was potentially misleading; the short was strictly about magic users in a non magic world and a pen shop. Some nuances reminded me of several faery stories, that’s all. I happened to be thinking about those aspects when I posted.

Can’t wait for your next novel Mr. Kloos…Loved Terms and Lines very much. I hope your publisher does not rush you too much though…I am fine with waiting as long as the wait is worth it…if your publisher is pressuring you too hard, tell her anticipation is part of the fun…

elle hayes · July 20, 2014 at 4:34 pm

What an excellent young author you are…You got Luke Daniels to narrate your novels AND you drink Scotch AND you are protected by little dogs. Congratulations!

Billie Doux · July 23, 2014 at 1:10 pm

Finished “Terms” a couple of days ago, and immediately zipped through “Lines” as well. They were both terrific — thank you so much for several hours of enjoyable reading. I’m very much looking forward to the third in the series, and how dare you leave us with such a huge cliffhanger?

Ruben Gavilan · November 24, 2014 at 12:50 pm

I am certain I am not alone when I say if you ever get with an artist to create some concept art for your ships / drop ships. I would be completely into that purchase. Thanks for doing what you do man. its good work.

Grant Davis · December 12, 2014 at 3:57 pm

I think I have found my new author. I picked up Terms and Lines just four days ago, and I’m already half way through Lines. You writing style and the amount of detail you give is perfect for me. When I started ready Terms, it was late afternoon and the next thing I knew, it was three in the morning. 🙂 I just could not put it down. Keep up the AWESOME! work.

Quick thought, do vessels in zero g have weight? They certainly have mass.

dtrane13 · April 23, 2015 at 1:23 pm

I LOVE your books. I came in late and was able to read / listen to them at work and on my drive to and from. I will say this my wife has read around 100 books so far this year ( trashy romance and free books on Kindle included ). She is the reader and not me. I decided after getting her the unlimited on Amazon to try an audio book out and I found Terms of Enlistment and Lines of Departure. I couldnt stop I started trying other books and have been excitedly waiting Angles of Attack to come out. I was so excited that I bought the audio version instead of just getting the free Kindle unlimited or waiting for the free whispersync ( IF it comes out ). This is all to say that you books have gotten me into reading and I cannot wait for more and more and more to come out. Hell lets get a TV series going.

CheeryR · June 9, 2015 at 10:56 am

Thank you for a wonderful series! Was very happy to see Angles of Attack pop up on my Kindle, ready for a thorough reading! Very thankful that I made a decision to grab your Terms of Enlistment as I never looked back since..

Thank you!

Billy Blackerby · July 6, 2015 at 8:58 pm

I’ve only just started Terms of Enlistment, but after seeing Grayson receiving orders to report to Fort Shughart I felt compelled to thank you for memorializing Randy Shughart in that manner. Looking forward to the rest of the book. Thank you again!

    Marko Kloos · July 9, 2015 at 4:54 pm

    Thank you! And if you like it enough to continue to LINES OF DEPARTURE, you may notice a passing reference to Master Sergeant Gary Gordon in there as well. 😉

      Billy Blackerby · July 12, 2015 at 2:32 pm

      Stayed up until 3am last night finishing Angles of Attack. References to Michael Murphy and Gary Gordon resonated with my heart song. I really love the honor code that you inject into your fictional warriors.

      When can we expect #4? Keep up the good work.

Leonid Lando · August 2, 2015 at 11:03 am

Thank you very much for a wonderfull reading. Ochen chorosho.

Richard H. Randall · October 22, 2015 at 2:46 pm

My thanks for great writing, for the subject matter, for your willingness to do social interests,
and for recognizing some of America’s finest warriors. I am giving my copies of your first four books to my best old friend down south for Christmas and his birthday. I will re-supply as time and conditions allow-I know you have heard that from your time as a soldier.
May God bless you and yours.
