Sixteen-year-old Felicia Murphy has learned the pitfalls of letting the snakes in her head control her life, and she has no intention of letting them interfere in her future. She knows it's not her duty to dish out vengeance, but, oh, the temptation...
Battling near-constant headaches bites, but with Ryder by her side, she's able to keep the Fury at bay. She doesn't care that Meg, her biological-mother-from-hell, has escaped Mercy's prison and will be playing dirty to get Felicia on her side. What she does care about is having a perfect night at the prom and successfully debuting the new mentor room for the troubled kids in town. She refuses to play into Meg's sick, twisted games.
Lines become blurred when Felicia's best friend is brutalized. Felicia knows she could have prevented the pain if she had been willing to wield her one secret weapon. What once was black and white now becomes soiled with shades of gray.
Will this self-discovery encourage her to embrace her craving for vengeance? And if so, will Ryder be able to accept her for who she has become?
