The Door Into Fire
The Door Into Fire by Diane Duane follows Herewiss, Prince of the Brightwood, the first man in ages to bear the dangerous Power of the Flame yet remain unable to wield it. Torn between loyalty and self-mastery, he aids his closest friend, the dispossessed prince Freelorn, using learned sorcery and the help of Sunspark, a mysterious, gender-shifting fire-being, to break a siege. As Freelorn struggles to reclaim his throne, Herewiss must decide whether to commit fully to a human war or seek an ancient castle whose gateways to other worlds may finally unlock his magic. Blending epic fantasy, queer romance, and mythic adventure, the novel explores power, identity, and chosen bonds amid looming conflict.
