Just one year earlier, Cassidy's daughter, Maddie, was attacked by a creature who can change shape at will; a demon who was unleashed by human hands from its chains beneath The Protector, an ancient oak tree on the Christopher property. Dubbed the "Sweet Dreams Killer", the creature lulls its female victims into a dream state before crushing their bones from the inside out.

During a routine prison transfer, the creature escapes and warns Maddie through their telepathic connection that he's coming for her. In the dead of the night, Maddie calls her best friend, Robyn Warren, and their connection is abruptly severed.

As Robyn hastens to be with the only family she has, little does she realize that ancient forces are at work. The man she loves has a deadly enemy who hates him enough to have unleashed a demon against him, but who? Can she and Cass fight the evil created for the sole purpose of destroying everyone he loves? Can Cass risk loving another woman he could lose?

In the wake of newfound surrender to a love they can no longer fight, Robyn and Cass find they have everything they've ever wanted...except time.
