Arrowood is the most ornate and beautiful of the grand historical houses that line the Mississippi river in southern Iowa where the days are long and humid and communities are small and closed.

It has its own secrets and ghostly presence: it's where two small twin girls were abducted ten years previously - never to be seen again.

Now, Arden has inherited Arrowood, and she returns to her childhood home determined to establish what really happened to her sisters that traumatic summer. But the house and the surrounding town hold their secrets close - and the truth, when Arden finds it, is more devastating than she ever could have imagined.
