Just uploaded Bitter Glory, a prequel novella set in the Crimson Worlds universe (similar to Tombstone). Bitter Glory follows a young Augustus Garret as he confronts one of the greatest challenges he will ever face.
Keep in mind that this is a short work, a novella about a third the length of one of the novels. A little light summer reading!
It's live on Smashwords (https://www.smashwords.com/books/view/336645) and it should be available on Amazon and B & N by morning (Monday, July 15).
