Bad Blood

After an argument with her grandmother at her Maryland home, sixteen-year-old Ginny Marshall ? ?born rotten,? according to Gram ? gets high and runs away.  She turns up on the doorstep of Maggie Ryan and Nick O?Connor?s Brooklyn brownstone.  Her presence in Brooklyn is unsettling, but, more urgently, Ginny is a suspect in a murder investigation back home.  Maggie travels undercover to Maryland, where she searches for a killer as threads from the past threaten to unravel both families.
