Amber is the one real world, casting infinite reflections of itself - Shadow worlds, that can be manipulated by those of royal Amberite blood. But the royal family is torn apart by jealousies and suspicion; the disappearance of the Patriarch Oberon has intensified the internal conflict by leaving the throne apparently up for grabs. In a hospital on the Shadow Earth, a young man is recovering from a freak car accident; amnesia has robbed him of all his memory, even the fact that he is Corwin, Crown Prince of Amber, rightful heir to the throne - and he is in deadly peril . . . The five books, Nine Princes in Amber, The Guns of Avalon, Sign of the Unicorn, The Hand of Oberon and The Courts of Chaos, together make up The Chronicles of Amber, Roger Zelazny's finest work of fantasy and an undisputed classic of the genre.
