I like the idea of the book, it’s good to see a writer working on a war story that focusses more on the characters than the war. That’s something I try to do in a few of my stories (I don’t plan on having these ones posted until I can get a bigger following... they’re a little abstract) and it’s a great way to have both a good story along side a great war. Something that’s great about the gaming series Mass Effect is it’s focus on the characters more than the battles. You’ll sometimes want to take characters with you more about their personality than their abilities. Your story seems like it can have that same type of power to it. I hope this helps!
