Gideon Coxall was a good soldier but bad at everything else. Now the British Army doesn't want him anymore. So when he hears about the Valhalla Project it seems like a dream come true. They're recruiting former service personnel for excellent pay, no questions asked, to take part in unspecified combat operations. The last thing Gideon expects is finding himself fighting alongside the gods of the ancient Norse pantheon. The world is in the grip of one of the worst winters it has ever known, and Ragnarok - the fabled final conflict of the Sagas - is looming.
