Despite successfully securing a balance between the competing magics of Wellmet, Conn is not happy. Duchess Rowan has promoted him to ducal magister, but the other wizards see him only as a thief.
But something sinister is brewing, as magicians' locus stones are being stolen and magical spells are going awry. As Conn faces old enemies and powerful magical forces, is he strong enough to save the city he calls home?
Diana Wynne Jones, author of Howl's Moving Castle, praised this middle grade fantasy series filled with magic and wonder, saying of the first book: "I couldn't put it down. Wonderful, exciting stuff."
