Meet the newest professor at Gooseberry Bluff Community University of Magic, Joy Wilkins. She may suffer from face blindness, but Pleasure can still acknowledge people by reading their auras – a skill that will come in particularly handy for her real work as an undercover agent with the Federal Bureau of Magical Affairs. Her objective: to find the foundation of weaponized demons being trafficked through the quaint college for the border of Minnesota and Wisconsin, and to locate her predecessor, the school’s missing History of Magic professor. And her analysis gets under way, the brutal murder of Joy’s handler – and mentor – models her over the trail of the secret society referred to as the Thirteenth Rib. Using the clock ticking down to the next strike, Joy will have to find fresh allies and reveal historic secrets if she’s likely to have any potential for defeating a conspiracy that threatens to kill the whole planet.
