Remy Pendergast and his royal vampire companions return to face an enemy that is terrifyingly close to home in Rin Chupeco's queer, bloody Gothic epic fantasy series for fans of Samantha Shannon's The Priory of the Orange Tree and the adult animated series Castlevania.

Remy Pendergast, vampire hunter, and his unexpected companions, royal vampires Lord Zidan Malekh and Lady Xiaodan Song, are on the road through the kingdom of Aluria again after a hard-won first battle against the formidable Night Empress, who threatens to undo a fragile peace between humans and vampires. Xiaodan, severely injured, has lost her powers to vanquish the enemy's new superbreed of vampire, but if the trio can make it to Fata Morgana, the seat of Malehk's court—dubbed "the Court of Wanderers"—there is hope of nursing her and bringing them back.

En-route to the Third Court, Remy crosses paths with his father, the arrogant, oftentimes cruel Lord of Valenbonne. He also begins to suffer strange dreams of the Night Empress, whom he has long suspected to be Ligaya Pendergast, his own mother. As his family history unfolds during these episodes, which are too realistic to be coincidence, he realizes that she is no ordinary vampire—and that he may end up having to choose between the respective legacies of his parents.

Posing as Malek and Xiaodan's human familiar, Remy contends with Aluria's intimidating vampire courts and a series of gruesome murders with their help—and more, as the three navigate their relationship. But those feelings and even their extraordinary collective strength will be put to the test as each of them unleashes new powers in combat at what may be prove to be the ultimate cost.
