In the bitter winter of 2009, following the death of their grandmother, Erica Calcott and her sister Beth return to Storton Manor, a grand and imposing Wiltshire house where they spent their summer holidays as children. When Erica begins to sort through her grandmother's belongings, she is flooded with memories of her childhood - and of her cousin, Henry, whose disappearance from the manor tore the family apart. Erica sets out to discover what happened to Henry - so that the past can be laid to rest and her sister, Beth, might finally find some peace. Gradually, as Erica begins to sift through remnants of the past, a secret family history emerges; one that stretches all the way back to turn-of-the-century Oklahoma, to a beautiful society heiress and a haunting, savage land. As past and present converge, Erica and Beth must come to terms with two terrible acts of betrayal - and the heart-breaking legacy left behind.
