I'm looking for books similar in story to The Witches and the Grinnygog, featuring an Idol Deity/God.

Ever since I first read a Pathfinder Adventure Path, watched the TV series of The Witches and the Grinnygog, and read the book it's based on, I've been fascinated with Idols.

Unfortunately, they are a rarely used element, as far as I can tell, in the world of fantasy, and a number of times the Idol is villainous, the Grinnygog was delightfully benevolent though.

Are there any fantasy books with Idols, hoping for benevolent, but OK with wicked, as a major element?

I'm trying to write a story with the subject, and I want as much inspiration as I can get.
