Rating: 3.5. 
 I really wish Goodreads allowed half-stars. Do you ever find yourself struggling to rate something because you think it's closest to a 3, but for some reason you find it more memorable than something you rated a 4, and so-on? And then you wind up re-evaluating a bunch of older ratings? I think I give this a little too much thought, haha. 
 Anyway - this was a fun story that kept me hooked, but I wasn't always crazy about the writing style. I can forgive that, though - this is Malerman's first book and he's a musician first and foremost. But there also seem to be a few loose ends that never get tied up, leaving the ending feeling incomplete. 
 I really did enjoy it, but in addition to the above, not knowing what to make of a certain character really bugged me. (view spoiler)[ Was Gary really immune? Or did he go mad and somehow avoided murder/suicide? Either way, I want to know why, although I know that the main character never finds out, herself, and she's our narrator. (hide spoiler)] I tend to like things tied up neatly at the end unless ambiguity REALLY works for the story. In some ways it did here, but in others, it felt like things just dropped off. 
 It also really bugged me that (view spoiler)[ we never get to actually see the creatures. I get that that's pretty much the whole point but I wanted to know what they looked like, darn it! (hide spoiler)]
