Alecto the Ninth - Tamsyn Muir

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.
