Here are a few you might like to add to your own book marketing strategy:
"Where authors and readers come together."
Author Marketing Club
"Join thousands of authors who want to promote their books. Free book marketing resources and tools."
"A search engine for books."
"Tell us what you like and we'll match you with a book."
"Publish. Read. Get Read."
"Where writers meet readers."
Good Reads (of course)!
"Meet your next favorite book."
"A Home for your books."
There are hundreds more and I'm slowly working through the list. It does take some time and effort to list your book on these sites so pick the ones that have the most traffic and match your needs and your book's genre the best. I will share more as I find and submit Deep Deceit to them. I only recommend sites that I have successfully added my books to so you won't waste your time clicking on sites that no longer exist or aren't accepting any new additions.
If you're not an author looking for ways to market your book but an avid reader looking for ideas, these sites are meant for you too! If anyone would like to add any, please feel free to do so. Happy reading and writing :) As I said, there are more to come as I plug away at my marketing activities.
