Advertising APoS-Derry

I don't know if I'm doing this right, but I bought postings through an influencer, of sorts, to see what can happen. Here's a sample of what got put up, along with links to many others:

I'm also considering buying a display slot at the London Book Fair, in March, as well as contemplating buying a review from Kirkus Reviews, but need to look into that, more.

The thing is, I want APoS-Derry to get noticed and I don't have the power of a mainstream publisher to get it out there. So I'll have to sink some money into it. Question is, how much can I afford?

Not a lot. But after working on this book for more than 20 years, it may be what's called for.
