Definitely a solid offering, and one with near-perfect pacing. I do wish the author had managed to resist the temptation to make the bad guy as evil as possible.

I never intended to read this entire book yesterday but once I started I could not walk away from it.

Imagine someone showing up on your doorstep one day and explaining that the child you and your wife had two years ago, the toddler you love and cherish, isn't your biological child...that a mistake had been made at the hospital during a chaotic and traumatic delivery.

Being a mother both biologically and through adoption, I found this book riveting, thoughtful, and terrifying. The questions regarding nature versus nurture and whether parenting is defined by biology or the heart were so personal for me.

J.P. Delaney can do no wrong in my eyes, I love everything he has ever written, including under his pseudonyms, and this is his best to date, without question.

**And don't worry there is plenty in here to keep the attention of those of us who need a little thriller in our books!

Thank you to J.P. Delany, Random House Publishing Group - Ballantine and NetGalley for giving me this book in exchange for an honest review.

TEN STARS to this author for the story, the characters, and the writing. What a book! I am amazed at the talent one individual can have in bringing a story to life in such a way that it leaves you feeling awestruck and mesmerized. One of the best books I have ever read, and I've read thousands. Thank you SO MUCH netgalley for the privilege of reading this advance copy. UTTERLY FABULOUS!!!!!!

Six stars! I have read all of JP Delaney's books and this one is the absolute best by far! I read this book over two days and could not wait to continue reading. What an amazing and frightening story. I don't know what I would do in Maddy or Pete's situation. This is one of the best books I have read in the past year. I cannot wait to recommend this book to anyone who will listen! Thank you to NetGalley and the publisher for the advanced copy.
