The bond is broken. Ascension is coming. The Advent is rising. And the enemy is winning. An ill-prepared world crumbles before the power of the Alpha Prime and his ascending Summer Omega daughter. Presidents and kings bow before Mareus as Advent pack numbers grow. In the wake of their severed bond, Kale and Shelby struggle to find meaning in their changed relationship—but it takes more than love to repair it. The keys of Ascension are held by the magical races that have found refuge on Earth, and the third key has been identified—but it is held by a mistrusting and often devious race. In order to claim it, Shelby and Athena race against each other on a journey that brings them face to face with a darkness never anticipated, the very darkness that destroyed Alsvoira. Long held prophecies and beliefs are shattered as the true meaning of the Advent begins to take shape. Earth may always have been a temporary refuge.

Shelby Brooks is the Summer Omega of whom werewolf Mystics have long prophesied, but prophecy can be altered. She and her bonded mate, Kale Copeland, have awakened and discovered who they truly were—and who they must become. Their former world of Alsvoira suffered the wrath of Mareus, the Alpha Prime, and his failed attempt to bring about the Advent through Ascension. Now on Earth, Mareus and his daughter, Athena, are determined to succeed in ushering in the Advent. Shelby must race against Athena to unlock the keys of Ascension before the Advent destroys all she loves. Her unique bond with Kale may give her an edge as she fights to save her pack and Earth, but Athena has plans for their intensifying relationship. All bonds, even those forged by prophecy and eternal love, can be shattered.

Nightmares are doomed to repeat themselves. Shelby Brooks learned she is a werewolf on the same night she learned that love and betrayal go hand in hand. She was sixteen. Now, going into her senior year in a new town, love is the last thing Shelby is looking for, but she finds herself irresistibly drawn to Kale, the son of an Alpha. As her heart slowly reopens to the possibility of happiness, threats mount and her very presence brings mortal danger to Kale and his entire pack. Is her destiny to be a savior? Or a harbinger of death, as the Summer Omega prophecies foretell? Shelby Brooks must reach deep within and discover what lies there, something she fears to unleash.
