The Beast Within - Knights of White, #1

ONLY PASSION CAN SOOTHE THE BEAST WITHIN... Known only as Jag, he leads the Knights of White against the soulless Darkland Beasts who took his wife and his life. Jag is immortal, destined to live with the vengeance he feels in his heart and the dreams that haunt his soul. Sensual dreams of a woman. Dreams that threaten to unleash the beast within.... Karen Gibson is an innocent mortal, unwittingly thrown into this millennia-old battle, and--unwillingly--under Jag's protection.
She and Jag are about to discover that they have met before--in the dreams they share. Neither trusts the other. Neither can survive alone. The secret of those erotic dreams may be all that saves them--if Jag can only accept it. At risk is Karen's life. And Jag's immortal soul... Previously published with Harlequin.
