I finished the Narn i Hîn Húrin the other night before bed. Not sure it is the kind of thing you want to finish before going to bed, it is such a devastating tale.
The tale has no happy ending, and possibly one of the saddest endings ever, but it is a good tale nevertheless. Not only is it well crafted, but it is properly aligned with the moral polarities of the universe.
And it has these drawings and watercolors by Alan Lee. It really is as close as any book gets to perfection, it seems to me.
