A wild misfit in the human world, Nettle is enthralled by the glamor of the faery realm, with its two moons and scarlet stars. She grows close to Conor, a human stolen centuries before, and she also falls under the spell of mysterious Ellion, a shadow faery. To try to help her beloved grandmother who is fading in her world, Nettle makes a pact with the faery king. He'll heal her grandmother in exchange for Nettle completing three tasks. She agrees, not realizing that deception lurks in this enchanted place, and that she has been tricked . . .

In this dangerous fantasy kingdom, Nettle discovers--too late--her part in an age-old love story . . . and the price she will pay.
