The fourth novel follows Corwin and the remaining princes of Amber as they use their superhuman powers to defeat their brother-turned-traitor.Returning to Shadow Earth to investigate a threat against his life, Corwin discovers that the Jewel of Judgment has been stolen by his traitorous brother, Brand, who plans to use the gem to reshape the universe.

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.

All Hail King Oberon! At last, Dworkin has created the magic Pattern, and Amber has been established with its own myriad of shadow worlds. Now, King Oberon works on repairing Castle Amber after winning his epic battle with the forces of Chaos. And his world is at peace . . . until he is attacked by a nightmare creature that refuses to die, while everything in its path withers and turns to dust. Oberon leads the monster away from Amber, on through an almost infinite number of Shadows, and still the creature presses ever closer. At last, Oberon travels to the world of the Pattern itself—his source of power—to make a stand against it. His fight, from the center of the Pattern, rips the world asunder—even damaging the Pattern itself. But Oberon manages to defeat the deadly monstrosity . . . and the Pattern repairs itself. Still, much time has passed, and much damage has been done. Among other things, when Oberon returns to Amber, his father tells him that the Pattern has been magically transported to the bowels of the castle. Further examination reveals that the original Pattern remains where it was drawn, and Castle Amber now possesses its identical double. But more damage than that may have been done. In a single evening, Oberon discovers that Amber hosts another race of creatures—a whole civilization living beneath the ocean in a mirror duplicate of Amber. He learns that it, too, has had a copy of the Pattern appear in its depths, that the Queen of the undersea kingdom knows all about him and desires him to get rid of the Pattern from her realm; and that she has plans for him . . . and the powers to perhaps make her wishes real. “Fans of the late Roger Zelazny’s popular AMBER series should flock to this...”—PUBLISHERS WEEKLY

Awakening in an Earth hospital unable to remember who he is or where he came from, Corwin is amazed to learn that he is one of the sons of Oberon, King of Amber, and is the rightful successor to the crown in a parallel world.
