The Mating Rite by Bonnie Vanak
Ten years ago, Darius Bryant fell in love and lost his mate before they consummated their union. He mourned her death and moved on, but innocent, carefree Samantha always possessed his heart, no matter how many women he had in his bed. When the sexy werewolf shifter discovers Samantha is alive, he becomes determined to claim her as his forever mate. He must convince the now-cynical Samantha that her heart, body and soul belong to him.
Samantha Evers spent years waiting for Darius to return, and thought he'd forgotten his promise to make her his own. She's vowed to live as a human, for she fears the sexual savagery of the wolf life. Now Darius is back and the only act that will seal them together is the intense sexual bonding of the mating rite. She will fight hard to resist Darius' sensual allure and his tender words of passion. But a far greater problem awaits them both when they discover someone wants Samantha out of Darius' life for good, and will stop at nothing until she is dead...
