** spoiler alert ** 
 On one hand, I enjoyed the main character and found her interesting. On the other... About half the book is written like the script for a reality tv show. I like survival shows, so I read it. But even I skipped the five pages detailing the squirrel deaths. 
 The entire gimmick is that Zoo doesn't realize she's not on a reality show. She manages to deny a weaponized ebola outbreak for 2/3rds of the book. I get it, it's a coping mechanism, but it's a really irritating one. 
 My biggest problem with the book. The ending. It ends before the reunion, it ends before Zoo even knows her husband is alive. There's no denouement, and no satisfaction. I mean, yeah, it's an easy scene to imagine, but I love reading tearful, "But I thought you were dead!" scenes. Nope. Not here. The reader knows everything will sort of work out, but the character doesn't. Actually, writing this, I'm removing a star.
