The Gormenghast Trilogy

New cover edition can be found here

A doomed lord, an emergent hero, and a dazzling array of bizarre creatures inhabit the magical world of the Gormenghast novels which, along with Tolkien's Lord of the Rings, reign as one of the undisputed fantasy classics of all time. At the center of it all is the seventy-seventh Earl, Titus Groan, who stands to inherit the miles of rambling stone and mortar that form Gormenghast Castle and its kingdom, unless the conniving Steerpike, who is determined to rise above his menial position and control the House of Groan, has his way.
