As the title says, I am looking for an app to allow me to create iBook publications as well as edit iBook books created with the OSX version of iBook Author. There may not be one that exists. I have looked, but so far, I have only found one (Book Writer - eBook, PDF creator), but I am not impressed with the screenshots and I cannot tell if I can edit existing iBooks Author projects.

Would be nice if Apple would recode iBooks Author for the iPad.
