Masquerade in Lodi (Penric and Desdemona, #9)

Bastard’s Eve is a night of celebration for most residents in the canal city of Lodi -- but not for sorcerer Learned Penric and his Temple demon Desdemona, who find themselves caught up in the affairs of a shiplost madman, a dangerous ascendant demon, and a very unexpected saint of the fifth god.
This novella falls between “Penric’s Fox” and “Penric’s Mission” in the internal chronology of the Penric & Desdemona tales.
