This novel had me completely engrossed from the start and on the edge of my seat, to the point where I couldn't read it at night for fear of having dreams about it (you definitely wouldn't want to be a character in this book). I'd have to take breaks to catch my breath and do something else for a bit, it is that tense. Alice Feeney does a fantastic job of creating an atmosphere that feels so real.

Similar concept to And Then There Were None, but a very original and surprising ending that makes you want to reread the whole thing.
