I'm looking for something to read. I'm interested in ecclesiastical settings like churches and gothic cities. But the most important thing I look for is the inner thoughts and evolution of the main character: his/her feelings of guilt, regular visits to the confessor, self-comfort drawn from faith, praying God/saints, relapses and self-loathing as well as his/her process of "waking up".
I know it's something very particular and there's a lot of junk literature about the topic with poor writing and archetype characters, but if you have read anything of good quality, I would be very glad to know.
Thank you in advance.
