The man who murdered Gaillynn Amirah's lover is out of prison, and he's not finished with Gaillynn's family. He knows the secret of their treasure. He's determined to take it for himself.

At the heart of Locket Manor, on the rocky coast of Maine, is a powerful, mystical stone. For generations, the Amirah Diamond has been a blessing and a curse to the Amirah women. It bestows them with long lives, superior strength, and ageless beauty. But such gifts come at a cost: The women are imprisoned in their life near the stone. And anyone who dares to love them will die.

If they lose the stone, Gaillynn will never find love again and her mother will continue to be tormented by a secret-not to mention that Gisela, who may hold the cure for Earth's faltering environment in her teenaged hands, will not survive to fulfill her destiny. The Amirah women aren't the only ones who could be destroyed by the theft. A shift in global power and the fate of a dying planet depend on Gaillyn's courage to protect the stone, face dark truths of the past, and silence a thief determined to claim the power of the Amirah Diamond.
