I love when a book dives right in, it's what thrillers are made of. Nancy Bush doesn't disappoint. It is already getting the wheels turning in chapter 1 wondering who wanted to go after the babysitter, did they know the sister's switched places? Where was Cooper since Jaimie never found him at the party? Why is Emma so scared and has never mentally fully recovered from that night? What is in store for the sister's now that they are reunited? I love getting so many questions to start with and read as they unfold to the end.
