Memphis, 1939. Twelve-year-old Rill Foss and her four younger siblings live a magical life aboard their family's Mississippi River shantyboat. But when their father must rush their mother to the hospital one stormy night, Rill is left in charge--until strangers arrive in force. Wrenched from all that is familiar and thrown into a Tennessee Children's Home Society orphanage, the Foss children are assured that they will soon be returned to their parents--but they quickly realize the dark truth. At the mercy of the facility's cruel director, Rill fights to keep her sisters and brother together in a world of danger and uncertainty. Aiken, South Carolina, present day. Born into wealth and privilege, Avery Stafford seems to have it all: a successful career as a federal prosecutor, a handsome fiancé, and a lavish wedding on the horizon. But when Avery returns home to help her father weather a health crisis, a chance encounter leaves her with uncomfortable questions and compels her to take a journey through her family's long-hidden history, on a path that will ultimately lead either to devastation or to redemption.
