Two years ago, Ava Garrison's cherished two-year-old son Noah disappeared from a house full of party guests. There was no ransom demand; his body was never found. Most people assumed that Noah drowned after falling off the dock of their Church Island home into the Pacific Ocean. 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, 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, or the new handyman who always seems to be there when she leaves the island. 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.
