I just released an ebook Publisher’s Pack for books 1&2 of Mage Errant, to link with the audiobook via Whispersync. It doesn’t contain any new material besides a new afterword, so no need to go out and buy it immediately, but if you don’t own the ebook yet, it’s a dollar cheaper than buying books 1&2 separately! It’s also available on Kindle Unlimited.
The cover is a modified version of the audiobook cover, which I’m pretty happy with!
