The Song of the Quarkbeast by Jasper Fforde (The Chronicles of Kazam, book 2)
A book review by Faith Thompson
Jennifer Strange thought her troubles were over when she killed the dragon and Big Magic showed up to fix it. But now she and her handful of insane wizards at Kazam are locked in a power-struggle with their rival magic company, iMagic, and preparing for a competition — rebuilding the bridge in the city entirely by magic.
When their most reliable sorcerers begin to be arrested and the Amazing Blix takes over the position of Court Mystician, Jennifer suspects foul play. It will take a Quarkbeast, a mysterious woman named the Once Powerful Boo, a missing ring, the Transient Moose, and Jennifer’s sort-of boyfriend Perkins to fix this mess — and the bridge.
