So how do you pick books?

[labingi]

I'm starting to market the book version of The Hour before Morning, and I'd like folks' input on the most effective methods for attracting interest.

If you're not already in a fandom or buying the works of an author you know, how do you choose books? I suspect a common way is rec's, like Amazon, etc., which I hope will be of use to me eventually. But you have to have some sales and readers before these rec's will kick in, so where to start?

Are there places you frequent for book reviews? Other avenues you trust for alerting you to new works?

Thanks in advance!
