Didn't like the ending. If i knew it was a novel about war i probably wouldn't read it. 
 Edit: Two months after finishing this book I have added a star to my review. I was a little disappointed after finishing the book because i expected something extraordinary and didn't know it was going to be so war-related. But now that I've got a perspective, i have to say the plot twists were awesome, the story was awesome, the lonesome and dark atmosphere was INCREDIBLE and the ending was good and this book is one of the best novels I've ever read. I'm gonna read Silo series too(also by Hugh Howey) and I have put this book in my favorite shelf.
