This is a graphic novel adaptation of the tale Roland tells of his youth to the Ka-tet during
Wizard and Glass, which has always stood out as one of the highlights of the series to me.
The artwork is of a very high standard and the style suits the tone perfectly. Naturally, many of the details are merely glossed over here, and I wouldn't recommend this to anyone who hasn't already read the novels, but as a primarily visual retelling I think it works pretty well as its own entity.
