Awakening (Timeless #4)

Cheyenne has done the unthinkable and fulfilled her mother's destiny through marrying Marcus.

Although she believes it's the key to his defeat, her family does not. Shunned and abandoned by everyone, even Callon, she must come to grips with her choice and push forward for a new, brighter future.

Yet the fight has only just begun. As Marcus gains more and more control over Cheyenne, hungry for the powers she's kept from him, her family are placed in greater and greater danger. And if she can't find his weakness in time, he'll use her to eliminate the remaining Timeless clans forever.
