Twelve years after the conclusion of Poison, Balthazar and his brothers initiate a plan to bring about the destruction of Dessa and her friends. The lives of the Keepers are threatened constantly, and Dessa realizes that once again, she is the key to everything. Dessa's past life as a Keeper comes back to haunt her when her memories begin to fully return after millennia of remaining buried in the darkness, and the harsh realizations she encounters just might be enough to break her. With nowhere else to turn, Dessa finds herself running into the arms of the very man she had vowed to destroy: Balthazar. Can Dessa rise to the challenge and expel her enemies for eternity? Or will she fall to her own darkness as she struggles to define the person she truly wants to be? With allegiances tested, the bonds of love broken, and the tenuous line between ally and foe becoming completely nonexistant, the Keepers are in for the toughest fight of their lives.
