I read and reviewed each of the three novellas collected here separately, so this is basically just for my own records. The collection rating was easy, as all the individual stories got three stars from me. They're a little slight, but they're also fun and fast-paced, and I can appreciate that. I can also appreciate how stories like these must spark kids' interest in mythologies, and help them to become aware of how those mythologies exist as continually changing narratives. The particular change featured here is that which occurs when two different world-explanation-systems meet and adapt to each other. That's something that still goes on today, and in many forms, so it's great that kids who read this series are introduced to the idea in a kind of low-stakes way, if that makes sense. Hopefully it'll help them to recognise systemic conflicts and changes when they come across them in real life, and be a little more open as to what those things can mean.
