Far as I can tell, as books have been removed from other vendors. I'll enroll the complete Red Sector Chronicles, including Dark Knight, on Wednesday, July 1st, into Kindle Unlimited. A White So Red, under my epic fantasy pen name K. D. Jones, will also be enrolled in KU on July 1st. This is a three-month trial run, at which point I may decide to go wide again with distribution. Snap 'em up while you can, KU'ers!
