Hunter's Moon (gollanczf.)

""My name is unimportant, but you can call me Jack. I'm a musician by choice, a magician by profession, and a bastard by disposition. I'd been doing the magic thing for about five years when they found me. They said I had a talent, that I was smart enough and fit enough and enough of a shit that I could serve my country in a way most people never even get to hear about. And I did want to serve my country, didn't I? I didn't really want to contemplate what might happen if I said no.""

And so Jack found himself on the front line of a secret war that most people simply wouldn't believe was possible, working for a secret organization tasked with defending England from whatever supernatural threat faces it. MI5 know nothing about it and would laugh if they found out--but they wouldn't laugh for long. Whether wiping out a group of demon summoners, infiltrating a coven determined to assassinate the prime minister, or rooting out a neo-Nazi sect who are trying to bring back Hitler from the dead, Jack is a very modern sort of magician--trained in a variety of the dark arts but also handy with firearms and skilled in unarmed combat and electronic surveillance. David Devereux has combined lightning action with dark supernatural thrills and produced a blistering new breed of supernatural thriller.
