A fantasy novel told in four parts. Khaim, The Blue City, is the last remaining city in a crumbled empire that overly relied upon magic until it became toxic. It is run by a tyrant known as The Jolly Mayor and his devious right hand, the last archmage in the world. Together they try to collect all the magic for themselves so they can control the citizens of the city. But when their decadence reaches new heights and begins to destroy the environment, the people stage an uprising to stop them.
