The Heart of Fire is a story about two brothers, Ferran and Yusef, who set out from their home in the city of Jhanal to find their mysterious mentor, Tala al-Sahara-Sitt. What they find is adventure, tragedy, and enough intrigue to bring down a kingdom. Enter the djinn, a race created by the ancient gods to oversee humankind, although betrayal, it seems, is not strictly a human trait and the magical lords of the realm of Ashur are menaced by their own problems and a prophecy a thousand and one years in the making.
