I'm currently working on producing large print versions of all my books. That's going to make a few of them pretty hefty, but I've heard from a few readers that they prefer bound, large print books as opposed to e-books which can increase font size.
Also, the audible version of Cult of the Great Eleven is nearing completion. Narration is done, it's just a matter of waiting for ACX to do their quality checks. Hopefully that will be wrapped up within ten days or so!
