Trickery by Sabrina York

Though seducing a mortal is expressly forbidden, novice witch Willow Ostreth wants one. Bad. Unbeknownst to Willow, Austin—the glorious, delicious specimen who makes her heart pound and her body weep—is no mere mortal. He’s really Damien DeWinter, a powerful warlock, a man determined to lure Willow—and bind her—to his bed.

When the luscious Willow breaks the rules and uses her magic to ensnare him, Damien—rebel, renegade, outcast from the Witching World—figures he has carte blanche to pursue her and seduce her using any means possible. And his arsenal is vast.

As they tempt and torment each other with pleasure, neither realizes there is a greater magic at work. One that could bind them together, forever.
