      About This Book

      Cassiopia Cassell's high IQ had always been too much for the men she'd dated. But now her beloved father was missing, and the only way to rescue him required she retain the services of a man with special abilities, a man she did not care for, and one she would have to convince to accompany her through an unexplained portal that led to dangers beyond imagination.
