There's a malevolent force in town, and it's quite literally Valerie Stevens' job to determine who's behind it and why they want to destroy Calgary. She'll have help, in the form of her best friend (now more or less a zombie, unfortunately), a powerful dwarf troll, and the ghost of former Canadian Prime Minister William Lyon Mackenzie King (but he goes by 'Bill' these days). But that's not all ? Valerie has some tricks up her sleeve and, she hopes, luck on her side. Oh, and her boyfriend, Dave. He drives a dump truck.
