I loved the ending of Hero of Ages. There's a novella to read partway through the second age that does some beautiful stuff around it. The second age is a very different style, but it is a lot of fun. You never regret that extra shake...
I just finished the Earthsea series by Ursula K. Le Guin. The first book is from the sixties and the final short from 2018, so it is a fascinating trip through the maturation of Fantasy. The first three books are firmly young-adult, while the last three stick with the characters as adults. The whole series ends with a very short story the author wrote to be published after her death. It's a wonderful look at the mind of an old person at the end of their story.
Recent publications include afterwords written in 2012 which give a lot of context and interesting insights into how she wrote stories.
