Pastoral Noir Trilogy, Book 1:

The Rev Pervert ('It's pronounced Purr-veer!') is happy in the small town parish of Saint Mary's Episcopal Church. As a priest and sex addiction counselor, he finds himself surrounded by people who either don't want to acknowledge sex, or can't talk about anything else. Into his country idyll comes the calamity of having his former mistress turn up at the local funeral home!
