eat husband, a psychopathic son, a beautiful newborn daughter, and catastrophic heart failure necessitating an organ transplant. When a serial killer becomes an unexpected organ donor, Casey gets a heart and a new lease on life.

Except, dark dreams plague the disgruntled housewife-places she's never been, chasing women she's never met. Sometimes, Casey wakes up outside her kids' rooms without realizing how she got there-knife in hand.

How far will a mother with a newly acquired taste for vengeance go to right the wrongs of an abusive husband, an increasingly violent son, and even her own sins? Only the heart knows what it truly wants.
