The Farthest Shore is the third book of the Earthsea saga and the final book of the "original" Earthsea books.
In my opinion The Farthest Shore is an excellent fantasy book. It's a timeless classic of fantasy literature and everybody who reads fantasy should read it.
The Farthest Shore is a bit different and darker from the previous books, but it's a great book. I think that everybody, who appreciates fine fantasy and good writing, will find this book interesting.
