From Library Journal

Merlin, whose blood unites the royal houses of the true world of Amber and the Courts of Chaos, becomes drawn deeper into the complex plots and counterplots of both worlds as forces conspire to place him on Chaos's throne--despite his own intentions. Zelazny's celebrated "Amber" chronicles (begun in 1970), of which this novel is the tenth, portrays the ultimate in virtual realities. With this volume, the author finds new grounds to explore and shows no sign of winding down to a conclusion. Filled with Zelazny's characteristically snappy prose, this title is recommended where the series has a following.
