Napryazhennoe, zahvatyvayuschie i filosofski nasyschennoe proizvedenie, v kotorom moralnye konflikty i masshtabnye idei opirayutsya na peredovye dostizheniya nauki. Dzheyku Sallivanu udaetsya obmanut smert. Stolknuvshis so smertelnoy boleznyu, on perenosit svoe soznanie v telo androida, chto garantiruet emu fakticheskoe bessmertie. To zhe samoe delayut i drugie milliardery. Blagodarya novoy protsedure mnemoskanirovaniya oni otpravlyayut svoi ustarevshie i obrechennye lyudskie obolochki v roskoshnyy tsentr na obratnoy storone Luny, a sami ostayutsya na Zemle v novyh telah. No ne vse idet po planu. Hotya novyy mnemoskan Dzheyk nahodit lyubov, nedostupnuyu emu ranee, ego vozlyublennaya stalkivaetsya s sudebnym protsessom: ee syn otkazyvaetsya priznat mnemoskan tem zhe chelovekom, chto i prototip, i trebuet nasledstvo. Tem vremenem na Lune biologicheskiy Dzheyk, blagodarya dostizheniyam meditsinskoy nanotehnologii, istselyaetsya ot svoey bolezni i reshaet vernutsya. Kto teper nastoyaschiy? Kto obladaet pravami lichnosti - biologicheskiy original ili kopiya, kotoroy on sam ih ustupil? I chto znachit byt chelovekom?
