A hostile relationship with her sister and a complicated past with her father's second wife have kept Robin estranged from her family for many years. But when her father's new family is attacked in their house, with her father and his wife in critical condition in the hospital, she returns home determined to put her experience as a therapist to use to help mend fences and care for her young stepsister, who survived the attack relatively unscathed. It looks like a random robbery gone awry, but as Robin spends more time with her family members, she learns they all had their secrets--and one of those secrets may have put them all in horrible danger.
