One of the things I kept thinking was that this book is zombie apocalypse meets M. Night Shyamalan. It was an interesting book, and I liked that there's this secluded village that the world has forgotten about. 
 I liked the world Ryan built- there's a clear hierarchy. While she doesn't completely explain everything that's happened, it is pretty easy to figure out. 
 The characters, though, fell flat. They were all really annoying, and it seems like this book is much more plot-driven than character-driven. And as much as I liked the plot, there were too many things going on. Keeping zombies at bay, romance, staying safe...her obsession with the ocean. She finally gets to the ocean, but it felt really lame and forced. 
 I give it a 2 out of 5. It reminded me too much of The Village by M. Night Shyamalan for me to really get into it.
