Request #391 From Moth H

I don’t think it was specifically YA but it *was* in my middle or high school library in the mid-2000s. High fantasy, probably published in the 80s or 90s. I may be mixing up several books here, but there are two things that stand out in my mind: first, there was a plotline where the personification of Death was in love with a Chosen One female protagonist, who had towering magical abilities. This was (I believe) a fantasy series, and this plotline would have been the overarching plot. The only other thing I remember is one of the books begins with several men traveling through a cave, which ends up being dangerous in some way, and one of the men is frequently swearing by his god’s balls (lol).
