In Riverworld, did you enjoy ...

... a motley band of pilgrims whose clashing agendas and backstories collide during a perilous journey?

Hyperion by Dan Simmons

If what hooked you in Riverworld was trekking upriver with Burton while juggling Twain, Alice, and even a repentant Göring, you’ll love how Hyperion assembles seven pilgrims bound for the Time Tombs and the Shrike. Each traveler’s tale reframes the quest—just as Burton’s expedition keeps being redefined by who joins it—turning the group’s frictions into momentum and revelations.

... a centuries-spanning odyssey of reincarnated souls exploring civilization’s rise, fall, and renewal?

The Years of Rice and Salt by Kim Stanley Robinson

Drawn to Riverworld’s grand scope—every human reborn along an endless river, civilizations blooming around the Grails, and Burton’s long arc toward the tower? In The Years of Rice and Salt, recurring souls (B, K, and I) meet across lifetimes—from Timur’s wars to Chinese oceanic empires and Islamic scientific renaissances—probing fate, meaning, and history with the same sweeping ambition.

... big-idea debates about engineered afterlives and the morality of those who run them?

Surface Detail by Iain M. Banks

If the Ethicals’ godlike experiment in Riverworld—resurrecting everyone and testing humanity—sparked your curiosity, Surface Detail dives into virtual Hells where entire civilizations imprison souls. As Lededje Y’breq seeks justice and Culture Minds wage a shadow war over afterlife ethics, the book interrogates the same thorny questions of who gets to play god and why.

... the unnerving, unanswered puzzle of an inhuman-made landscape and its perilous artifacts?

Roadside Picnic by Arkady Strugatsky

Compelled by the central riddle in Riverworld—who built the resurrection world, what is the tower, why the Grails?—you’ll be riveted by the Zone in Roadside Picnic. Stalker Red Schuhart navigates lethal anomalies and alien detritus toward the Golden Sphere, seeking answers that remain tantalizingly out of reach, capturing that same eerie, awe-filled mystery.

... audacious revelations that recast godhood, identity, and death through dazzling, reality-bending ideas?

Lord of Light by Roger Zelazny

If Riverworld’s audacity—resurrecting everyone from prehistory to Burton and Twain—gave you a thrill, Lord of Light delivers that same rush. On a colonized world where tech makes ‘gods,’ Sam (Mahasamatman) rebels against a pantheon that controls reincarnation. The dizzying set pieces and idea fireworks evoke the wonder you felt chasing the river’s source.
