This book is a collection of three short stories that reveal the origins of Fafhrd (story one), the Gray Mouser (story 2), and how they got to meet (story three).
There isn't much for me to say here apart from the fact that I didn't like these much. However, that's not because I though the stories were bad, it's just that they were too... shallow I suppose. There is no deeper world visible in the plot, only showing that which is right at the surface. The fault with that lies with the fact that these are short stories, who's pacing follows wholly different rules than a full novel.
I tired, but it's not my thing.
I won't be reading the remaining bundles, but do realize that this isn't because of a lack of quality. If you enjoy short stories as well as novels you can give these a spin.
