This is a book that serves its purpose well. It will suck you in from the first page. It's well written, haunting, filled with twists and turns and isn't altogether predictable. (Though for me, much of it was). HOWEVER... no one warned me, so I will warn every new mother (or any other person who just had a baby) DO NOT READ THIS BOOK. JUST DON'T. WALK AWAY AND COME BACK WHEN YOUR CHILDREN ARE IN PRESCHOOL.Take my word for it. Just trust me, because the ending of this book will make you sick to your stomach. Anyone besides that special group, if you love creepy, suspenseful, Dean Koontz type books, you will love it.
