Two years ago, Ava Garrison's cherished two-year-old son Noah disappeared.

There was no ransom demand; his body was never found. Ava, wracked with grief, has been in and out of mental institutions since that night.

Back on the family estate now, though, Ava is having strangely lifelike visions - visions of Noah on the dock of her island estate, or in his nursery. Visions that seem to be urging her to risk her own life . . .

Ava doesn't trust anyone now. Not her husband. Not her cousins. Not the servants her wealth is paying for.

They know more than they are saying. They appear to be anxious about her well-being. But the truth is more dangerous than Ava can imagine; and the price is higher than she ever thought to pay.
