Business in another world
This was brilliant. I really enjoy when a LitRPG/progression fantasy type story focusses on something different than fighting. In my opinion, business is a good story vehicle because it can have high stakes and measurable growth. With the setting of, modern person in a medieval fantasy world, you can do a lot of fun stuff in the realm of business. For me this book scratched the itch left behind by mercantile plotlines in Ascendance of A Bookworm.
Also Nemorosus is masterful at writing distinctly unique characters that feel real. Or at least compared to many of his contemporaries in this genre, Nemos characters are great.
