It has its own secrets and ghostly presence: It's where Arden's young twin sisters were abducted nearly twenty years ago, never to be seen again. Now, Arden has inherited Arrowood, and she returns to her childhood home determined to establish what really happened that traumatic summer. But the house and the surrounding town hold their secrets close. And the truth could be more devastating than Arden ever imagined. As the mystery unravels, the novel explores the reliability of memory, the stories we tell ourselves, and the power of love.
