The Emperor needs necromancers. The Ninth Necromancer needs a swordswoman. Gideon has a sword, some dirty magazines, and no more time for undead nonsense. Tamsyn Muir’s Gideon the Ninth, the first book in The Locked Tomb Trilogy, unveils a solar system filled with swordplay, cut-throat politics, and fierce lesbian necromancers. Her characters leap off the page, as skillfully animated as arcane revenants, creating a heart-pounding epic science fantasy.

Raised by unfriendly, ossifying nuns, ancient retainers, and countless skeletons, Gideon is ready to abandon a life of servitude and an afterlife as a reanimated corpse. She packs her sword, her shoes, and her dirty magazines, preparing for a daring escape. But her childhood nemesis won’t set her free without a service.

Harrowhark Nonagesimus, Reverend Daughter of the Ninth House and bone witch extraordinaire, has been summoned into action. The Emperor has invited the heirs to each of his loyal Houses to a deadly trial of wits and skill. If Harrowhark succeeds, she will become an immortal, all-powerful servant of the Resurrection, but no necromancer can ascend without their cavalier. Without Gideon’s sword, Harrow will fail, and the Ninth House will perish.

Of course, some things are better left dead.
