Yeah, I’d agree with that (although idk what Left Behind is). There was some level of criticism of Christianity throughout most of it, but the end sort of… yeah.

Tentatively started A Spectral Hue by Craig Laurance Gidney.

Finally finished Between Two Fires by Christopher Buehlman; I found it enjoyable and well-paced. Knight-turned-brigand and divinely-touched orphan tween go on a quest across France during the height of the Black Plague. Medieval fantasy religious horror; very heavily features Christian mythology, so if that’s not your thing, skip. Do check content warnings.
