Joseph Lake doesn’t know who he is or where he came from... and the answer might just be the death of him. By day, Joseph scrubs toilets and fixes broken light fittings. By night he looks into weird stuff: local hauntings, unexplained disappearances, satanic cabals dancing naked around ancient stone circles. The usual. The Uncanny calls to him like a beacon, and he follows its signal wherever it leads, hoping that one day it will shine a light on who he really is. So far the clues haven't added up to much, but now a mad woman is stalking him, he’s tripping over dead bodies in the street, and he keeps having terrifying apocalyptic visions. Can Joseph put the pieces together and figure out his identity? And if he does, will he be able to live with who he really is?

Life was a whole lot easier back when Joseph was an oblivious idiot. Up until a few days ago, the worst thing Joseph had to deal with was mopping up vomit in the hospital he works at. Now he’s discovered that monsters exist, and he’s expected to mop those up too. Joseph is a warlock, or so he’s told, yet he can barely pull off a convincing card trick, let alone magic away evil. Which would be fine if he didn't have to contend with the ghost of a dead sweetheart, debt-settling demons, and murderous standing stones. Can this clueless warlock be counted on to save the day, or is this a mess he can’t clean up?

A long time ago, Joseph woke up next to a lake with his past scrubbed from his memory. Now, ten years later, secrets will be revealed. It’s time for Joseph to discover the truth of his mysterious past, but for that to happen, it seems he’ll need to embrace his dark destiny. And that’s not all poor Joseph has to deal with. There’s also a spate of bizarre animal slaughters sweeping the area, a strange man who believes something monstrous is taking over his village, and a blossoming romance that may or may not be tainted with pure evil. This is it. The end game. The place this story has been heading, right from the start. At long last, Joseph is about to learn his origin story. But when he discovers the truth, will he reject his old ways, or will he finally give in and become the Magic Eater?

Children are vanishing, and their lives rest in the hands of two unlikely saviours: a witch who can’t practice magic, and a talking fox who can’t stop dying. Joseph Lake, the last remaining witch of the Cumbrian Coven, is back, only now he has to get by without his mentor. He’s going to have to rely on his own abilities to defend the people he’s sworn to protect. Oh dear. The only clue as to the whereabouts of the missing kids points to a landmark known as Demon’s Mark, a mysterious pair of indentations in a rocky outcrop that legend says are hoof-prints left by the devil. While investigating Demon’s Mark, Joseph finds himself up to his neck in talking corpses, diabolical demons, and a pair of wicked siblings with a thirst for hellish power. Will Joseph and Barnabas—his furry, axe-wielding sidekick—be enough to stop a century-old scheme from reaching fruition, or are the stolen children gone for good? Read Demon’s Mark now for a fast, funny, page-turning tale of monsters and magic that you won’t want to put down.
