For millions of years, Mkgor, the god of vampires has remained inert, locked in fossilized rock, its influence unfelt by the innocent, daylit world. But now, all of that has changed and the world will know Darkness as it has never experienced before.

Lord Edwin, Lady Eliza, and their half-breed son Oliver are set to face the greatest challenge of their lives, and there are no guarantees that they or any of their motley supernatural crew aboard the Queen's Gambit will survive this latest assault. With enemies on all sides, the steamvamps, the shifters, the Fae, and the Mechi-people have their work cut out for them. Some will fall. And some will be changed in ways that can make monsters of men.
