If you are a Fantasy author and you are interested to promote
your book, I created on Shelfari
a group where you can meet and discuss with your readers. The advantage of Shelfari is that you can add your books to the group shelf and ask readers to review and comment them. More comments you get, more visibility you get in one of the bigger social network of book readers.
So, if you are interested, join Shelfari and access the Fantasy Published Writers
