Catherine Sterling thinks she knows her mother. All her life, it's been just the two of them. But now, Catherine is ready to spread her wings, move from home, and begin a new career. Ruth Sterling thinks she knows her daughter. Catherine would never rebel, would never question anything about her mother's past or background. But when Ruth's desperate quest to keep her daughter by her side begins to reveal cracks in Ruth's carefully constructed world, both mother and daughter begin a dance of deception. No one can know Ruth's history. There is a reason why Ruth kept them moving every few years, and why she was ready - in a moment's notice - to be gone in the night.
