I've finished the third and fourth entries of the saga.
In "The Farthest Shore" the magic is running out of the world; Ged and the prince of Enlad part in an adventure to find out what the problem is. It's a book full of adventure, visiting many Islands in the archipelago.
In contrast, "Tehanu" has a slower pace. It's a fantasy novel in which dragons and magic are not in the foreground. It answers the question How does the dispossessed, children, women, handicapped, live in a world with magic? And doing so makes you think about the power relations in the so called real world.
