Much has changed in the sky-city of Quentaris. With the Archon dead, dark forces have come into play. New faces are appearing, familiar ones vanishing, and the horrid Florian has claimed the throne. Then, as Quentaris slips quietly through a vortex into the watery world of the Yarka, Tab Vidler and her friends suddenly realise they are the city's only hope. Plots, intrigue, magic, mystery, high adventure and more - everything that you've come to expect from the Quentaris series.
