Brimstone Summary & Overview

Saeris has survived Zilvaren, crossed the quicksilver, and claimed a throne inside Ammontraíeth’s Black Palace. But ruling the Blood Court means facing vampires who question her heart, her blood, and the Fae warrior standing beside her. Her first edicts are barely spoken when corrupted feeders breach Cahlish, carrying a black rot that devours magic, land, and everyone it touches.

With war closing in, Saeris must master volatile Alchimeran runes capable of shaping metal, opening gates, and breaking ancient spells. Kingfisher hunts for silver and answers while the secrets of his true name—and the oaths attached to it—threaten to turn him into an enemy’s weapon. Their bond may be the only thing strong enough to hold two realms together, but every bargain demands payment. As hidden books surface, forgotten heirs rise, and a dragon’s judgment waits beyond a corrupted gate, Saeris must decide what she will sacrifice for peace—and what she will never surrender.
