I found a site that might be of interest to you. The site is Viqua Games, and it allows you to create your own Hide N Seek games. I made one for Sew Deadly, the bi-weekly newsletter for the embroidery book series, featuring the latest cover, Stitch Me Deadly. Be sure and check out the game on Wednesday, Sept. 22.
This might be a fun way to promote your books on your site on in a blog post. I think it's cool!
