If you loved how Titus Groan immerses you in the labyrinthine halls, traditions, and rituals of Gormenghast, you'll be drawn into the alternate-historical England of Jonathan Strange & Mr Norrell. Clarke's novel offers richly textured worldbuilding, with arcane societies, ancient legends, and a sense of place so vivid it becomes its own character.

If you appreciated the gradual, atmospheric pacing of Titus Groan, with its focus on mood and the slow development of intrigue, you'll find Shadow & Claw equally mesmerizing. Wolfe's tale follows Severian through a decaying, baroque world, building a haunting, slow-burn narrative that lingers in your imagination.

If the cast of oddballs and grotesques in Titus Groan—from Steerpike to Dr. Prunesquallor—delighted you, you'll relish the wild array of characters in The Master and Margarita. From the sardonic devil Woland to the hapless writers of Moscow, Bulgakov's cast is chaotic, memorable, and endlessly entertaining.

If you were captivated by the brooding, gothic mood and grotesque details of Titus Groan, Perdido Street Station will sweep you into the grimy, nightmarish city of New Crobuzon. Miéville crafts a world as eccentric and oppressive as Gormenghast, teeming with bizarre creatures, corruption, and wonder.

If you were fascinated by the inner lives of the Groan family and the stifling, insular atmosphere of Gormenghast, you'll find We Have Always Lived in the Castle haunting. Jackson's novel explores the fragile mental states and eerie rituals of the Blackwood sisters, drawing you deep into their isolated world.
