Hi! Gray 1 is on sale now, and through the 12th of September, for .99 US everywhere--all countries, and all vendors.
Barnes and Noble
Also, I've written "The End" on the first draft of Oil Apocalypse 5, the final installment in that series. Now I have to revise it, edit it, proofread it, and then my pro proofreader will work on it. It should be out by October 10 or so, with a pre-order period on Amazon and Google Play for sure (the other places, I've never tried a pre-order, so I won't promise you that until I see how it works!)
Thanks for reading and enjoying my books.
