A personal record...

... I don't think I've ever been working on FIVE books at the same time ever before. Currently in-process are:

Light of Reason: The next Jason Wood novel/collection, this one starts with "Bait and Switch" and so far includes "Burnout" and, in process, "Feet on the Ground", with one bridge section. Not sure if there'll be one or two more pieces in this one or if those will be for the third and probably last purely Jason collection. 

Adventurer's Academy: The story of a group of would-be Adventurers at the often-mentioned Academy during the same time period as my other fantasy series on Zarathan, featuring Lalira Revyne and Spinesnarl Mudswimmer from my short story "The Adventurer and the Toad". 

The Impractical Quest: The tale of Enochlis Book-Bound, a bilarel (ogre) who wants to be a wizard despite the limitations of his people. Enochlis is seen also in the second book of the Spirit Warriors trilogy.

Articles of Faith: Fifth book in the Arenaverse series, picking up shortly after Shadows of Hyperion left off. 

Unity of Vengeance: Xavier Ross actually gets to go after the people who killed his brother.
