Unfortunately, I feel as if I am better at writing reviews for books that don't work for me so I am endeavoring to change that up. I absolutely and without reservation love this novel. 
 Not only do I think that is Slaughter's best work yet, but it's also the best new book and new-to-me book of 2015, displacing a few others as my possible 2015 picks. Also in a year where I've read mostly sub par works, what a treat to read an incredible story that made me laugh and cry. I rarely cry during reading novels; I think I became immune to tears during my previous career as a therapist, so when a novel can get me that wound up, it's a very good sign. 
 Further, all of my emotions were running high while also running in all directions: never have I read a book where I absolutely loved a character in the first chapter only to absolutely detest that same character in the last chapter -- that's a mix of talent and hard work when a writer manages to strike that delicate balance. I don't want to give a lot away because the plot is the best - a perfect storm of twists, character-development and a tight plot that makes you question everything that you've read before. 
 The sum-up: Just read it, you'll be glad you did.
