This book might not have an actual plot, or characters beyond paper-thin cutouts, but by damn it does have opinions about the logistics of starting a small business with mythological basement-dwelling partners and I respect that. (...I mean, not necessarily all of the opinions themselves. But I respect that it has them!)

That does sound interesting! Especially because the mythological magical business partners have to be kept a secret, which makes it hard to explain your business plan to outsiders. And good luck dealing with inspections ^^
