What's a fantasy book/series you love that you struggle to recommend to others?

Look, not everyone's tastes are gonna align. Sometimes you like something that not everyone is gonna enjoy, whether that's for thematic reasons, character reasons, or events that occur in the book.

For me, it's gotta be Thomas Covenant. Love, love, love the series but the opening can (very justifiably) turn a lot of people off of the book(s), and I struggle to recommend it without a lot of caveats and warnings.

So what's yours?
