If you loved the sharp wit and playful humor in Mort—especially Death’s dry one-liners and the gleeful send-up of fantasy tropes—you’ll be delighted by Good Omens. This book is packed with hilarious banter, absurd celestial bureaucracy, and a charmingly irreverent take on the apocalypse. The unlikely partnership between the angel Aziraphale and the demon Crowley is every bit as funny and heartwarming as Mort’s misadventures with Death.

Just as Mort explores what it means to live, die, and take responsibility for the souls of the departed, The Graveyard Book follows Bod—a boy raised by ghosts—on a journey through the mysteries of life and mortality. The book gently probes big questions with warmth and whimsy, much like Pratchett’s thoughtful yet lighthearted treatment of Death’s domain.

If you enjoyed the playful, unpredictable magic in Mort—from Death’s horse Binky to the odd rules of the Discworld’s afterlife—you’ll find a similar sense of delightful chaos in Howl's Moving Castle. The magical world is full of surprises, with enchanted doors, capricious wizards, and spells that rarely go as planned. Sophie’s adventures in and out of Howl’s mysterious moving castle are both whimsical and enchanting.

If Mort's evolution from a bumbling apprentice to someone who shapes the fate of the universe resonated with you, you'll love Sourcery. It follows Rincewind, a cowardly wizard, as he’s forced into situations far beyond his comfort zone, leading to real growth and change. Like Mort, Rincewind’s journey is full of comic mishaps, but also genuine moments of personal transformation.

If the imaginative and bizarre worldbuilding of Discworld drew you in—where Death has a house and the afterlife is bureaucratic—Neverwhere offers a subterranean London teeming with strange characters, hidden dangers, and its own peculiar logic. The world feels alive, layered with history and darkly comic surprises, much as Ankh-Morpork and Death’s realm do in Mort.
