(Book)

"Emma is a loving wife, a devoted mother--and an involuntary killer. For years she's been hiding the dead body of the teacher who seduced her as a teen. It's a secret that might have stayed buried if only her life had been less perfect. A promotion for Emma's husband Alex means they can finally move to a bigger home with their young son. But with a buyer lined up for their old house, Emma can't leave without destroying every last trace of her final revenge"--Dust jacket flap.
