The cover really drew me in and the synopsis clinched it. I remember the "babysitter killer" myth from when I was a teenager. It always spooked me when I was babysitting. I would love to read a book based on this common urban legend. It sounds very intriguing with the sisters and them looking back on the even twenty years ago. I love the type mysteries where a killer starts back up after a 10-20 years. This definitely sounds like an enjoyable and exciting book!
