Finder's Bane

Finder's Bane, by Kate Novak and Jeff Grubb, is the fifteenth book in The Harpers series. It later became the first book in the plane-spanning The Lost Gods trilogy.

"When Joel became a priest of the new god Finder, he knew it meant forfeiting the honor and security of his position as a master bard. Now his freedom and his very life are at stake as powers of evil embroil the priests of Finder in a struggle against a plot to resurrect the dead god Bane.

With his only allies the young freedom fighter Holly Harrowslough, the mysterious winged woman Jas, and the aging priest Jedidiah, Joel embarks on a mission to recover the Hand of Bane. His quest leads him from the Realms all the way to the extra-planar city of Sigil. There Joel must rely on all his courage, wisdom, and strength to thwart the return of Bane the Tyrant and rescue the god Finder from imminent death."
