Dear Marko,
Thirty minutes ago, I finished reading Centers of Gravity. Before then I have done very little beyond eating, drinking, and reading since I opened Terms of Enlistment. Your books have made me feel such emotion that I have not felt in so long.
It’s been years since I’ve read anything that moved me quite as much. I now dread opening another book because I know almost anything else will be drab and dreary in comparison.
This may all sound ridiculous but I simply did not expect what I initially assumed to be a by-the-numbers military sci-fi series to affect me in this way. This makes me want to write something myself, which I have never before considered. I bet it’ll be rubbish though.
I have relished following Andrew across his adventures. Even when I correctly predicted what was about to occur, you kept me on the edge or threw in a twist. Halley might be my favourite character in fiction. I feel like I can close my eyes and become these people.
To anyone reading this and rolling their eyes, I get it, but please give these books a try and I hope you feel something like I do right now. It’s barely been a week but I feel like I’ve lived a lifetime in a simultaneously horrifying yet wonderful universe.
Thank you, Marko.
You’re welcome, and thank you very much. I’m glad you enjoyed the story so much to feel moved to leave that lovely review. (And do check out the Frontlines: Evolution series if you haven’t started it yet. It has a new protagonist, but you may see some familiar faces popping up here and there…)
Will you be posting any of your worlds on StoryverseStream? If so, please let us know so we can follow more in-depth.
Khan is my new favorite character in world cards I hope he gets a stand alone novel
December 2026 for Cygnus release. Good timing. I’ve got a week off at the end of the month. I know what I’m going to casually do.
I just started the Frontline series, as a Michigander I appreciate the mention of “some town in Michigan’s Upper Peninsula.”
I binged Palladium Wars & Frontline series last year whilst travelling so I’m very excited to see that #5 of PW is on its way! Also thought worth commenting that I rewatched love death and robots recently and was pleasantly surprised when checking the credits!
With all due respect I highly encourage you to denaturalize and head on back to deutschland if you’re gonna keep calling people Nazi. As they say from your part of the world auf wiedersehen.
OMG. Jack, how drunk do you have to be to make this dark and stupid comment here?
Yikes, dude.
We certainly know from the response that, how do the teenagers says it, ‘someone is butt hurt’. Being a little older, I view the perceived insinuation on the matter of relocation as an admission of guilt. We know how you voted Jack.
1.) I shared a quote that said nobody can be intelligent, decent, and a Nazi. You need to take a long, hard look into your soul and ask yourself why you felt I was talking about you. Then ask yourself what it is about your life that makes you want to post “go back to where you came from” comments on strangers’ blogs at half past one in the morning.
2.) I’m an American by choice. I’ve been a citizen for almost 22 years. This is my country too and I am not going anywhere. You don’t want to hear that Nazis are bad, *you* go ahead and leave, like those morons from TX who got sick of wokeness and moved to Russia.
3.) As they say from my part of the world: fuck off.
We’re not gonna fumble the bag on Reconstruction a second time, Jack, so you might want to think about that.
Hi there from Wallis. I discovered the Palladian Wars series as a kindle recommendation after finishing one of Christopher Nuttall’s books. So downloaded all four, and life stopped while I read them. Then I discovered the Frontline series and have just finished book 8. Absolutely enthralling. A big thank you. Happy New Year.
Just finished the Frontlines series. I just wanted to say thank you for writing it. I really enjoyed it. As a retired AC-130U pilot, it really resonated with me on many levels.
Going to guess 99% probability of spoofing conduct. Marko mentioned a few weeks back he was recovering from finishing Cygnus, and is likely incommunicado on some tropical beach sipping profoundly alcohol-riddled drinks with little umbrellas in them.
Incommunicado in New England, sipping profoundly alcohol-riddled drinks with little umbrellas in them.
someone claiming to be you has sent me three emails asking “I’d really love to connect, hear about your journey, and trade thoughts on the craft we both care so much about.” is it really you or are you being spoofed?
It was Scalzi.
It was not me. There’s a whole lot of publishing-related scamming going on right now where people send emails and social media DMs to readers and pretend to be well-known authors.
Oh, and if you engage with them, they’ll try to sell you something–editing services, or personal VIP fan club access, or some shit.
