Intriguing concept; cheesy execution. You know when you grimace when you see some guy singing karaoke and belting his heart out to girl ballad? You just can't turn away, right? That being said, I breezed through the book, and it did keep me guessing. I just hate those one liners that seemed to show up at the end of each chapter. Such as,

"I can't stop thinking about that smile she gave us, that sneer. It was almost triumphant. We need to get away from here. We need to get away from her."

[Suspenseful music. Fade to black.]

I don't recommend this book if you can't stand this type of writing, obvs. But if you just want a fun, suspenseful read, give this a try. Maybe you'll solve the mystery faster than I did. ;)
