You liked how The Punch Escrow treats teleportation like a real, explainable technology—and then uses Joel Byram’s duplicate to poke at identity and personhood while a mega-corp tries to erase the anomaly. Permutation City pushes that to the limit: Paul Durham orchestrates a world of software “Copies,” runs brutal thought experiments on their consciousness, and even spins up entire simulated universes to test whether a copy is as real as the original. If Joel’s two selves made you wonder who gets to live a life, Egan’s mind-bending, meticulously reasoned tale will scratch that same itch.

If Joel’s language-nerd snark and quick, irreverent asides in The Punch Escrow kept you grinning even as assassins and drones closed in, you’ll vibe with We Are Legion (We Are Bob). After Bob Johansson is turned into an AI and duplicated across spacefaring probes, he wisecracks his way through first-contact puzzles and existential copy crises—much like Joel defuses danger with wit while outsmarting a corporation that wants his “extra” self erased.

Beyond the chase and corporate cover-up, The Punch Escrow lingers on Joel and Sylvia’s strained marriage and what their choices mean once teleportation breaks reality’s rules. Version Control takes that intimate, philosophical lens and runs with it: Rebecca and her physicist husband’s “causality violation device” quietly warps their lives, pushing questions about memory, consent, and the ethics of world-altering tech. If Joel and Sylvia’s personal fallout drew you in as much as the science, Palmer’s thoughtful slow-burn will resonate.

You raced through Joel’s run-for-your-life scramble in The Punch Escrow—ducking corporate hit teams, hacking systems, and trying to protect Sylvia after a teleportation mishap splits him in two. Dark Matter delivers that same momentum: Jason Dessen is abducted into a universe-altering experiment and must fight his way back to his wife Daniela, navigating high-stakes science and relentless pursuit. If Joel’s peril felt like a rocket, Jason’s odyssey will keep your pulse spiking.

If the big oh-no moment in The Punch Escrow—when teleportation doesn’t destroy Joel but duplicates him, exposing what the corporation has been hiding—hooked you, The Fold aims at the same sweet spot. Mike Erikson is sent to audit a secret project nicknamed the Albuquerque Door, a “teleportation” breakthrough whose successes don’t add up. As he peels back the layers, the experiment’s true nature explodes into reality-bending consequences. It’s that same thrill of discovery and dread when the science does something no one intended.
