I love how we're delving more and more into the world and getting more details about John along the way in each of these stories.
The mythology of the rakshasha is fascinated and detailed. I also, especially, liked how John is mistaken for a loup-garou and the further world we get shown because of that.
I liked how poker was incorporated into the story, it wasn't just a backdrop for the plot to take place against. It was an intricate part of the plot.
I'm beginning to get really excited for this series.
Overall Prequels Thoughts (0.1-0.7)
While most of these stories stand alone well, I would recommend reading the 1st and 2nd together, and the 6th and 7th together as well (and don't expect everything, or even the main thing, to be tied up and resolved in these last couple). They're snapshots in John Charming's life, and a moment in time while he deals with a new monster. I'm intrigued and pulled in, while still being somewhat frustrated, and am looking forward to reading the first full-length novel, Charming.
I'm really excited to learning more about the world, the knights, John, and what the hell is going on with the open-ended stuff left hanging from these last two short stories!
