This is some of Zelazny's finest work. It is all of the Amber novels in one volume. They are incredible stories of the courts of chaos and the city of Amber. There is all kinds of sibling side stories and fighting. There is political intrigue, and magic. It is a little of everything put together masterfully.
Amber is the one real world, casting infinite reflections of itself-Shadow worlds that can be manipulated by those of royal Amberite blood. Unfortunately the royal family is torn by jealousies and suspicions. And the disappearance of the clan patriarch Oberon, has intensified the conflicts by leaving Amber's throne apparently up for grabs.
