Angel Isle by Peter Dickinson
This is a sequel to The Ropemaker, but takes place 20 generations later. Saranja returns to her decimated homeland after some type of magical catastrophe. There she realizes that the epic tales from her childhood are true, and that she, along with cousin Maja and a young man named Ribek, must seek out The Ropemaker to reign in the people performing bad magic.
I found this book to be long, tedious, and boring. I didn't care about any of the characters, didn't like the references to the magical Ropemaker and his clan of magicians (made little sense without the original), and I really don't see the teen appeal. Nay.
