I love Sara Shepard and the 'Pretty Little Liars' series, and this is in a similar vein - perhaps a little darker. The story centres around a girl, Emma, who takes over the life of her dead long-lost twin, Sutton. There are a few twists and turns along the way, as to be expected from Ms Shepard, and of course the inevitable 'cliff-hanger' ending. I am not sure if I want to read more in this series, so I would have preferred more of a resolution to the story. Still a good read though, if you know what you're letting yourself in for. If not, you might be seriously underwhelmed...
