Dark Wolf Rising (Harlequin Nocturne Series #152) (Bloodrunners Series #4)

Eric Drake, a powerful Dark Wolf, has never trusted himself around human females—preferring to mate only within his pack. That is, until he encounters Chelsea Smart snooping around Silvercrest pack land in search of her missing sister.

Secretly, Chelsea thinks Eric is the sexiest man she's ever seen, though she is wary of his potent Alpha energy. Then it's discovered that Chelsea's sister is being held by a pack of vicious Lycans, and Eric heroically leaps into action. Now, Chelsea will risk everything—her body and soul—to surrender to the passion that will mark her as Eric's woman for all eternity…if they survive.
