The Replacement by Brenna Yovanoff

Little kids are being taken and someone, or something, is being left behind in their cribs.  If you live in Gentry, you accept that this happens, whether you like it or not, because it's a cycle you can't break...
This is the story of a freak named Mackie Doyle, of a sister who loves him anyway and friends who accept him as he is.  It's a story filled with horror, mystery, sadness, love, pain, and an unlikely champion who changes the course of events in Gentry forever.  If you like stories that mete out answers in little bits and drips and leaves you wondering at the end, then this one is for you. 343 pp
