The Road To Amber, the last in the series, covers the final five years of Zelazny's career in the early 1990s, when he reached for new ideas and continued familiar themes with stories such as "Godson" and "Godson: A Play in Three Acts," two more Wild Cards stories ("Concerto for Siren and Serotonin" and "The Long Sleep"), and a linked sequence of five Amber stories leading to planned but unwritten Amber novels.
