The Society of Children's Books Writers and Illustrators (SCBWI.org) also helps promote the community of artists, writers, and book enthusiasts together by launching fun and exciting promotional events, conferences, and raffles.
SCBWI has created this amazing promotional tool called “Book Blast." I am participating and have a link that goes directly to my book profile page. (http://www.scbwi.org/bookblast-display/?id=413999)
