I found this book enjoyable. As best as I can remember, it does seem to be compatible with the other novellas about the character backgrounds.
The stories are well told, although I’ve always felt that graphic arts media usually have too fast of a pacing, this one didn’t seem bad.
One issue I had was that the backstory of Amos Burton seemed odd. I believe it is symbolic of his inner mind. But it doesn’t seem to fit with the style of the book overall.
