Saltwater Witch is mentioned on The Comics Beat! I’m in the most popular list on iBooks. The first two chapters are free, and sure my work is listed as an oddity, but Anne Rice and I are the only one’s called out by name in the article (and in bold!).
The rest of the list consists of free oddities, like Chris Howard’s SALTWATER WITCH, interspersed with paid warhorses, like WALKING DEAD.
