Book 1 of The Tale of the Five
"Good strong stuff with the right light touch." (Terry Pratchett)
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 dearest friend, Freelorn, exiled prince of Arlen. Herewiss does have a talent for more mundane sorcery, and (aided by the unearthly creature Sunspark) he uses it to rout the armies besieging Freelorn. But now Herewiss faces a devastating choice.
His time to master the blue Fire is running out. Should he join Freelorn in his fight to regain his kingdom? Or should he seek out the ancient keep in the Waste where doors lead into other worlds -- perhaps even the door whose use will teach him to control the Power that he must master or die?...
The Door Into Fire, on the strength of which Diane Duane was twice nominated for the John W. Campbell Award for best new writer in the SF/fantasy field, is the first volume in a series that has become a cult classic of fantasy for its unique take on sword and sorcery and its unforgettable characters.
