Can I get the Apple IBook Author on the New IPad

Will the ibook author be available for the new iPad? I've got a MacBook but its easier to use the iPad because of a disability.

I use an ibook creator on the iPad at the moment, but I would much prefer to use the Apple Ibook creator.

I haven't actually published anything yet and I'm thinking that it would be better to use the ibook author, so I can submit it straight to the ibook store.

Also, does anyone know if there are any proofreading and editing tools that I could use, as it is very expensive getting someone to do it for me. I had a quote of around £850 for a 100,000 word book!

Thank you. Any help will be most appreciated :)
