If you loved exploring the dense, layered world of Severian's Urth—with its decaying grandeur, lost technologies, and enigmatic societies—you’ll be drawn into Viriconium. Harrison’s city is a shifting, surreal landscape filled with cryptic customs and history, immersing you in a world as rich and strange as anything in The Book of the New Sun.

If Severian’s morally ambiguous actions and complex motivations fascinated you, you’ll be riveted by Gully Foyle’s relentless, often brutal quest for revenge in The Stars My Destination. Bester crafts a protagonist whose decisions are as captivatingly unpredictable and morally grey as Severian’s.

If you were captivated by Severian’s introspective journey and the philosophical puzzles woven through his narrative, you’ll be spellbound by Engine Summer. Crowley’s tale of Rush That Speaks invites you to ponder the slipperiness of truth, memory, and identity in a beautifully written, dreamlike future.

If the sense of awe and strangeness in Severian’s world—where ancient technology feels like sorcery—captured your imagination, you’ll find The Dying Earth irresistible. Vance’s stories brim with inventive magic, faded civilizations, and a haunting sense of time’s passage, much like the world Wolfe created.

If you enjoyed questioning Severian’s account—his selective memory, his imperfect honesty—then The Book of Skulls will intrigue you. Silverberg’s story is told through four shifting, deeply subjective narrators, keeping you guessing about what’s real and how much you can trust any of them.
