Full disclosure, I was a betareader for this anthology.
I also will admit that one of my many faults is that I have a huge soft spot for gnolls, so take into account my biases here!
Gnoll Tales is a great little collection that examines gnolls, rather than as the demonic, bestial figures as depicted in D&D, but rather as a race with their own culture, desires, and most of all, stories.
There's quite the variety, from an exploration of gender, to creation myths, to an interspecies wedding, to the discovery of something from a time of gnoll legend. If that last one doesn't make you shed a tear, I cannot name you gnoll-friend!
If I have a complaint, it's that a lot of the stories stick a little too close to standard D&D for my liking regarding the surrounding world and its races, but that's a personal opinion. It is nice to see, though, that not all other races see them with hostile eyes, but as just another people they can interact with.
The cover being rather adorable is also a plus. :)
