Eons ago, vampires tried to turn the dark Fae to harness their magic, only to create a demonic enemy more powerful than they could have imagined. Now, the Vampiric Fae are on the move, hunting anyone in their path. As the war with the vampires ratchets up, Myst, Queen of the Indigo Court, enshrouds New Forest in her chilling grasp.

Cicely Waters, owl shifter and Wind Witch, has rescued the Fae Prince Grieve at a great cost. Their reunion has lost them the allegiance of the Summer Queen--and the tolerance of the vampires. In desperation they turn to the Consortium for help. Now, to regain the good will of Lainule, they must dare to enter the heart of Myst's realm. But as Cicely and Grieve embark on their search for the heartstone of Summer, Winter is already wreaking her terrifying revenge.
