I wanted to read this since it was the inspiration for much of the original dungeons and dragons. I see now that it's mostly in the world building, and that being pulled from Welsh mythology leaves little credit to the book itself.

There are some funny moments but ultimately the dialog felt forced and overly formal, the plot moved more due to accident and coincidence than the efforts of the characters, and the characters themselves felt flat. It's a product of it's time, I suppose.
