Wow. Where to start? I picked this up thinking that it would be a light, engaging read but I was so, so wrong. This is probably by far the creepiest book I’ve read in a really long time. Unexpected twists and turns made this a pretty solid read. Zoe scared the bejesus out of me. My God. Some of the things Zoe did were terrifying and disgusting, and their friendship was almost disturbing. Cara was weak and accomodating, and actually really irritated me, but as nother reviewer suggests, had she been any other way the story wouldn’t have panned out as beautifully as it did.
