I just finished Marko's 60-page short, "Measures of Absolution", which uses Cpl. Jackson as a viewpoint character and picks up her story at the tag end of the "Battle of Detroit".
Good pacing (60 pages was gone before I knew it,) with some very solid action scenes, and it answers some nagging questions about the big firefight in Detroit that were left hanging in the original novel, while opening the door to a whole new storyline in the same universe.
More words, Marko. Faster! Now!
