I have a recommendation for fans of Fantasy, The Deverry Cycle by Katherine Kerr. It's a massively interwoven story of a group of souls reincarnating over centuries in the land of Deverry which is based off of Celtic myth and legend. It's REALLY long, contains over a dozen books and was written over the course of 20+ years. The overall story ending was a bit weak, but I really enjoyed the series as a whole and every individual slice of the overall story fits together really well.
