This book started out really strong. The beginning had a really good buildup to what was happening. And then it started falling apart. The second half and especially the last quarter of this novel fell into some real cliched happenings. Seriously, got too romancey. I know its YA but I have to think when you are nearly dying everyday and most of the world is dead you are not really thinking about your highschool crush all that much. That's just weird. I wish the author had worked on building the core elements of the story instead of a wishy washy romance followed up with some real teen angst. Stop that. Go kill some aliens instead. Probably won't read the next in the series.
