I read a book when I was young (late 80s early 90s) that I remember bits and pieces of, but can't remember the title.
The book starts off with a young woman's body being pulled from the water in a fisherman's net. A storyteller on the boat begins to tell the story of a young boy. I think his name was Tim, but could be wrong about that. He had a happy life with his family until he was forced to leave. He went on a journey which included him living in a cave in the mountains that was populated with blind amphibians that sang beautiful songs and told stories to him. They would lie in his lap and he would ladle water over them.
I don't remember the rest of the journey, but it turns out that
the story teller was actually the boy (Tim?) and the sea captain was the villain who had killed the girl, and Tim had hunted him down to avenge her.
Possible titles could be "The Body in the Net", "The Woman in the Net".
