In the grim darkness of humanity’s future, even noble blood won’t protect you from what lurks in the depths…
Seventeen-year-old Paric Kilhaven had his life mapped out as a noble scion in the towering hive-city of Hydra Secundus, but that life ends when he’s attacked in the city’s lawless underhive and infected with a mysterious substance that unlocks doors to another dimension.

Surviving the attack, Paric is thrust into a deadly game of cat and mouse. Working covertly for the Ecclesiarchy, he must navigate between rival hive gangs and corrupt nobles while investigating rumors of a Chaos cult. He soon finds a dire threat hidden in the underhive’s shadows—a Warp witch preparing to birth a daemon that could destroy everything Paric has ever known. Relying on outlawed powers, unlikely allies, and a determination to protect those he’s grown to care for, Paric must stop the witch before it’s too late.

Set against the backdrop of a rigidly hierarchical hive-city, “Psyker” offers a compelling exploration of unmatched power, politics and identity, where one’s existence is both a duty and curse.

Part adventure, part mystery, this dystopian science fantasy novel is appropriate for Adult and Young Adult readers.
