I wanted to share something I recently was introduced to because they are now following me on Twitter. Check it out!! They are a ebook publishing company that primarily publishes short history ebooks. I am trying to locate and will begin reviewing my research and hopefully getting into that market. You write your ebook and them submit a proposal to them. If they like it and think it would sell they publish and market it. You get royalties from sales. They work with apple apps!!
