The cover art is interesting. It invokes the feeling of someone is watching you. As a former teenage babysitter, I find that this book's concept plays on a common fear of being alone and something going wrong. What is unexpected could be deadly. It reminds me of that old tale of the phone ringing and the killer is inside the house. It's creepy and I love creepy. I can only imagine the twists that await in this story. I love timelines that are not linear as they are more interesting and help connect to characters in a different way. Inner thoughts and memories liven the pages.
