If you loved how stories like “Reason” and “Little Lost Robot” stress‑tested the Three Laws with airtight logic, you’ll sink into Permutation City. Egan pushes the puzzle to the limit—forked minds, simulated realities, and proofs of self that feel like Asimov’s coolest lab cases turned up to 11. It’s that same satisfying, step‑by‑step unraveling you got when Susan Calvin deduced why a robot behaved “impossibly”—only now the experiment is the nature of reality itself.

Enjoyed the way “Evidence” and “Runaround” let you solve the case by understanding the rules (the Three Laws’ hierarchy, the Mercury mission’s constraints)? Lock In builds its whodunit on the ironclad mechanics of an assistive tech ecosystem—integrators, neural nets, and legal definitions of agency. You get that same Asimovian satisfaction of watching a clever investigator apply system logic to crack an otherwise impossible crime.

If the linked-case, puzzle-box feel of I, Robot hooked you—Powell and Donovan’s field problems, Calvin’s clinical studies—Exhalation gives you a suite of precise thought experiments. Pieces like “The Lifecycle of Software Objects” mirror the ethical and behavioral testing you saw in “Liar!” and “Little Lost Robot,” while “What’s Expected of Us” and “Exhalation” scratch that same brainy, lab‑notebook itch.

If “Liar!” made you weigh empathy, deception, and responsibility, and “Evidence” blurred the human/robot line, you’ll be riveted by Do Androids Dream of Electric Sheep?. Deckard’s encounters with near‑indistinguishable androids force the same questions Susan Calvin wrestles with—only in a starker, moodier key—about consciousness, compassion, and the costs of enforcing rules on sentient beings.

If the debates around the Three Laws—especially in “Little Lost Robot,” with a tweaked First Law—made you think about who gets to set limits on sentient minds, A Closed and Common Orbit brings that ethical puzzle down to the personal. SIDRA, an AI placed in a single body, faces constraints that echo Calvin’s case studies, but the story asks how compassion, choice, and identity should shape the rules we impose.
