Mallory Vayle and her talkative skull, Maggoty, star in another fabulous adventure!

Mallory is getting to grips with her new powers and her new talkative friend, Maggoty. But when Maggoty sees a wig in Les Wigs shop, he just won't shut up about it! It's expensive, and no one seems able to pay Mallory properly for her cosmic services.

So her Aunt Lilith takes matters into her own hands, but in her quest to increase her own supernatural skills, she accidentally summons a Nightmare. It, inevitably, goes HORRIBLY wrong and Mallory must take a perilous journey into the bowels of Carrion Castle in search of the solution to Aunt Lillith's problem... But it's only when a bony fella with a scythe turns up (that’s Death – himself! – by the way) that she knows she and Maggoty are in for some terrifying fun and games!
