Amber

There is one true city, and its name is Amber. Every other world — yours included — is only a Shadow it casts, a rumor of the real thing flung out across the dark. The blood royal of Amber walk between those Shadows the way you cross a street, willing forests and cities and centuries into being as they go, and any one of them would cut a brother's throat for the throne. Roger Zelazny built his fantasy on that conceit: a family of scheming immortals, a staircase of infinite worlds, and a cold war of tarot cards and drawn steel strung between the perfect Pattern of Amber and the writhing Logrus of the Courts of Chaos. The heart of it is ten novels in two movements. The first five, beginning with Nine Princes in Amber, belong to Corwin — a prince who wakes amnesiac in a Shadow-Earth hospital and claws back his memory, and his crown, one betrayal at a time. The second five hand the telling to his son Merlin, a sorcerer as fluent in computers as in the Logrus. Around this core orbit shorter Zelazny stories and, after his death, other hands: John Gregory Betancourt's Dawn of Amber prequels reach back toward the realm's founding, alongside gamebooks and guides that map the castle and its Trumps — companion pieces, not the trunk. What sets Amber apart is its voice: first-person, hard-boiled, a demigod narrating cosmic treachery in the clipped cadence of a private eye who has seen everything and trusts no one, least of all his own kin. The scale is vast; the telling stays intimate and swift. Begin with Nine Princes in Amber and take the ten in order of publication — the two cycles run straight through, and the prequels, though set earliest, are best left until after you have walked the Pattern yourself.
