Sinful Ella and the Wolf

Why is The Prince of Frey suddenly unable to control the dark secret that could destroy him? When his wolf begins forcing itself to the surface on the full moon and racing off to a nondescript manor in the woods, his confidante thinks the wolf is seeking a mate. But Prince Jarrod won't risk his crown or a woman's life by trying to claim one. Meanwhile, beautiful servant girl Ella is being tutored in the ways of submissive pleasure, pain, and bondage at the manor by a pair of dominating mistresses who entertain wealthy noblemen for a living. Though Ella is not permitted a man's touch or the delights of orgasm, she learns all she can to some day please the man she will ultimately love. Amidst sizzling sexual encounters and royal house arrests, the pair forge a fateful bond that could unite them for eternity—or cost them everything.
