Dark Rider

An electrifying tale of deadly and forbidden desire that sweeps from the exotic islands of a tropical paradise to the magnificent estates of Regency England. Cassandra Deville's carefree life on the islands of Hawaii is shattered by the sudden arrival of a savagely seductive stranger. She's the key to Jared Daremount's plan to avenge his father, actually only a pawn in his plans, but once she becomes his captive, Jared realizes she's a prize he can never surrender.
