The Legacy — Katherine Webb

When they were children, Erica Calcott and her sister, Beth, spent their summer holidays at Storton Manor. Now, following the death of their grandmother, they have returned to the grand, imposing house in Wiltshire, England. Unable to stem the tide of childhood memories that arise as she sorts through her grandmother's belongings, Erica thinks back to the summer her cousin Henry vanished mysteriously from the estate, an event that tore their family to pieces. It is time, she believes, to lay the past to rest, bring her sister some peace, and finally solve the mystery of her cousin's disappearance.

But sifting through remnants of a bygone time is bringing a secret family history to light -- one that stretches back over a century, to a beautiful society heiress in Oklahoma, a haunting, savage land across the ocean. And as past and present converge, Erica and Beth must come to terms with two shocking acts of betrayal . . . and the heartbreaking legacy they left behind.
