I just listed SINFUL on goodreads.com and created a contest give-away for our novel! I'm just now trying to figure out the site, so there is not much on there yet, but I'm working on it. Please check it out and enter the contest!
Also, we have ordered posters for SINFUL and would love to have teachers and librarians display them in their classrooms. If you are interested in getting one (for free!), please let me know.
