The Seal of Sulayman

A half-human living in the world of djinn, General Bakr has always felt like an outsider. After two grueling years at war, Bakr is anxious to return to Earth and bask in the sunlight among his own kind. When he is reunited with his first love, Sheikha Sezan of Shihala, he realizes he still has feelings for her. But Bakr returned from the war with more than scars. A demon has made him her pet and the last thing she wants is to see him rekindle his old flame.
Sheikha Sezan, disenamored by her former love's abrupt departure and equally sudden return, is forced to come to terms with the terrible deal she made with a demon to keep him alive while at war. The demon, having kept up her side of the bargain, comes for Sezan's magic djinn fire as payment, but soon makes it clear she had no intention of giving up Bakr. Determined to save herself and Bakr from torment, Sezan sets out to find the Seal of Sulayman, a magical talisman that controls all magic.
The demon torments Bakr and Sezan, weaving a web of deception to keep them apart. With rival courtiers, monsters, a clever sphinx, and both of Allah's worlds working against them, only trust can rescue Bakr and Sezan from the demon's caprice. But communicating enough to trust each other is a difficult task when words ruin everything.
