Herewiss is the only man in centuries to possess the Power of the blue Flame, but he can’t use or control it — not even to help his friend and lover Freelorn, prince of Arlen, exiled from his native land and pursued across the Middle Kingdoms by the usurpers' allies. Invoking perilous sorceries and the even more dangerous assistance of the fire elemental Sunspark, Herewiss manages to rout the forces besieging Freelorn and his little band of followers. Together they flee east to seek brief refuge in the mysterious lands at the edge of the world they know.

But now Herewiss faces a devastating choice. His time to master the blue Fire is running out. Should he abandon his fruitless search and spend the time left to him with Freelorn in his loved's fight to regain his kingdom? Or should he seek out the ancient keep in the Waste where countless doors lead into other worlds—among them, perhaps, the door that when opened will show Herewiss how to break through into the Power he must master or die?...

The Door Into Fire, first novel set in Diane Duane's award-winning Middle Kingdoms universe, opens a fantastic saga of magic, adventure and love that has become a cult classic for its unique take on epic fantasy and its unforgettable characters.
