HE MADE HER HIS PRISONER... Ravishing, impulsive, and far too wealthy and independent for any gentleman to claim, Temple Longworth travels to the Arabian desert seeking adventure. And she finds it when she is captured by bandits and imprisoned in the lush oasis belonging to Sheik Sharif Aziz Hamid, also known as El Siif, The Sword.

...THEN SHE MADE HIM HER OWN Who is this dark prince who speaks perfect English and draws her with a power and a passion that defies logic or reason? She hates him. She desires him. She will resist him, unaware that he, too, is a captive--of the incomparable woman who has stolen his heart.
