Evie Tanaka is the put-upon personal assistant to Aveda Jupiter, her childhood best friend and San Francisco’s most beloved superheroine. She’s great at her job—blending into the background, handling her boss’s epic diva tantrums, and getting demon blood out of leather pants. Unfortunately, she’s not nearly as together when it comes to running her own life, standing up for herself, or raising her tempestuous teenage sister, Bea. But everything changes when Evie’s forced to pose as her glamorous boss for one night, and her darkest secret comes out: she has powers too. Now it’s up to her to contend with murderous cupcakes, nosy gossip bloggers, and supernatural karaoke battles—all while juggling unexpected romance and Aveda’s increasingly outrageous demands. And when a larger threat emerges, Evie must finally take charge and become a superheroine in her own right…or see her city fall to a full-on demonic invasion.
