Baby Teeth by Zoje Stage

Hanna is the seven-year-old daughter of Alex and Suzette. They love each other deeply and love their beautiful little girl. Their life should be complete except for two things - one is Suzette's battle with Crohn's disease and the other is the fact that bright and beautiful Hanna does not speak ever, to anyone. Suzette has done her best to give Hanna love and attention as a stay at home mom who must homeschool Hanna after she has been asked to leave several schools. Now it is getting worse and the tantrums and angry defiance have gotten physical and dangerous. Alex can't or won't see the hate and viciousness of his little girl playing right into Hanna's hands. Mommy is bad, Mommy is taking Daddy away from me so Mommy has to go. Suzette's life goes from perfect to something out of the Exorcist. This is a one sitting read! You will simply not believe the calculated violence that lurks in this seemingly well loved little girl.
Chilling debut!
