The study of the famed academic Donald Sex, sealed since the moment of his death, is about to open, and archivists are ready to dissect what he left behind. They are not ready for the macabre surprise that awaits them... moreEach of the Empire's houses keeps secrets, even from themselves.

The Locked Tomb series—Gideon the Ninth, Harrow the Ninth, Nona the Ninth, and Alecto the Ninth—is an epic science fantasy that blends necromantic theory and thrilling swordplay with a wicked, sacrilegious sense of humor; a modern mix of Dune, Riddick, and Gormenghast.
