I do support mystery bookstores. I bought almost all my books at my local mystery store, Nebula, in Montreal, until it closed. But so far, only one of those independent mystery bookstores has ever offered to advertise on this site.
Neither has Amazon, in fact, but they did at least offer to give me a percentage of any books I do sell through a link to their site. Not much, but it's more than almost anyone else has offered. And I do list any mystery bookstore that asks nicely, under Booksellers & Dealers in the Mystery Links.
And, of course, I'm more than willing to accept paid advertising from any independent mystery bookstore (or authors or publishers or whoever). More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
