If the way Rees puzzles through life-and-death problems near a neutron star grabbed you, you’ll love how Dragon's Egg imagines an entire civilization living on a neutron star’s surface. Forward explores how the cheela think, move, and build culture at 67,000 g and at blisteringly fast timescales—an idea-heavy, nuts‑and‑bolts complement to the gravity-driven hazards and makeshift engineering you enjoyed around the dense star in Raft.

If the jaw‑dropping moments in Raft—drifting habitats clinging to survival near an ultra‑dense star, strange ecosystems forming under impossible conditions—kept you turning pages, Rendezvous with Rama delivers that same wonder. Commander Norton’s crew enters the silent starship Rama and slowly uncovers its cylindrical sea, impossible ‘cities,’ and shifting microclimates, each revelation echoing the exploratory, mind‑stretching discoveries that Rees chases.

If you were hooked by the hard-scrabble survival in Raft—jury‑rigged tech, perilous traverses, factions under pressure—then Pushing Ice will hit the same nerve. When Bella Lind’s ice‑mining ship is dragged across interstellar gulfs by the moon Janus, the crew must ration air, improvise repairs, and navigate fraught alliances, much like the desperate, resource‑starved struggles Rees witnesses around the neutron star.

If the carefully worked-out setting of Raft—from the deadly gradients near the dense star to the practical tricks people use to survive—was your favorite part, Mission of Gravity is a classic in that vein. Clement crafts Mesklin, a world with crushing gravity at the poles and lighter gravity at the equator, and follows Barlennan’s expedition across it; every challenge and solution clicks with the same ‘this is how it would really work’ satisfaction you got from Rees’s hazardous forays.

If Rees’s drive to understand the universe’s strange rules—and the startling implications of those rules—was what you loved in Raft, Schild’s Ladder turns that dial up. After a physics experiment spawns a new vacuum state that begins overrunning our own, researchers like Tchicaya and Cass debate its nature and morality while racing to study it, delivering the same cerebral thrill of hypothesis, consequence, and cosmic stakes that Raft delivers around its dense-star crucible.
