Prudence Ann Wells grew up believing the things that went bump in the night were just fairy tales. Until the night a slathering beast with all-to-intelligent eyes breaks down their door. She freezes as the creature rushes her and her mother, convinced it can’t be real, as she and her sister, Justice, had always been told. Only they had been raised on lies. Prue survives the attack; her mother does not. Driven by guilt and revenge, she and Justice set out to stop the beast, but can Prue end the nightmare without becoming a monster herself?
