Double Down — M.R. Forbes

With the memory of their losses fresh on Hayley and Quark's minds, they head for a meetup with one of the only individuals in the galaxy who might be able to help them handle the coming storm. But the enemy always seems to be one step ahead of them, ready to intercept at every turn and forcing them to make even more sacrifices along the way. When they're put at a crossroads of trusting someone they don't or not trusting someone they do, they'll only have one choice: Lay everything on the line, soldier up, and double down.
