Rooks friend Xanth is facing a Reckoning for the crimes he previously committed as a former Night Guardian, and his friend Felix, leader of the ghosts of Screetown, continues to disappoint his father, the High Librarian. To complicate matters, Rook loses his memory once again, after being caught in a sepia storm. The fast-paced plot is made up of an interconnecting set of story lines, populated by a bewildering array of creatures that meet in a spectacular last battle. In the epilogue, an elderly Mire Pirate connects all seven books with an explanation of Rooks family tree.
