So, I have good news and bad news. The bad news is that White Mage #4 release on Audible got pushed back a bit, and is now scheduled for release May 17th. The good news is that White Mage #5 is scheduled for release on May 31, so you won't have to wait long to listen to the end!
On an unrelated note, the tale of Jack Myst is coming along nicely. In the last few years I've released my first book of they year in August, but this year I want to release it in July. Still working out the details, but it's looking promising. Stay tuned for the announcement regarding the title!
