Maddox Sinclair’s father told her to never trust a dryad. At the age of eight she learned why: dryads murdered her mom and dad before her eyes. Now at twenty-six, Maddox is freshly laid off and desperate—f or a home, for a future, and, as a type-one diabetic, for a way to pay for the insulin that keeps her alive. Utterly without options, she flees to the forest where her parents were killed to make a binding pact with a dryad queen: kill the queen’s immortal enemy, the Redwood King, and be cured of her disease before the broken healthcare system sends her to an early grave.

In the redwood treetops, adopted Prince Castor is plagued by a curse that kills anyone foolish enough to love him. It’s been a year since the Redwood King—a lover of cruel and twisted games—made Castor an offer he couldn’t turn down: get a mortal to fall in love with him by the Sylveris Solstice and be freed of his curse. But should he fail, he’ll be imprisoned for a year in the Tree of Exile, a place of dark magic that drives its inhabitants mad. Castor hasn’t had any luck yet…and with the solstice fast approaching, time is running out.

When Maddox mistakes Castor for the king, Castor knows this mortal stranger—who knows nothing about his curse— is his last chance at freedom. But while Castor will stop at nothing to seduce Maddox, she’s scheming to get him alone so she can drive her dagger through his heart. As the pair’s sparks accidentally kindle a romantic fire, Castor must decide: damn the woman he has feelings for, or give up his future and freedom? And can Maddox untangle the web of secrets she’s in before she kills the wrong man, or worse…falls for a cursed prince, sealing her fate once and for all?
