This standalone novella in the smart, snarky, and action-packed Heroine Complex series follows personal superhero trainer Lucy Valdez and friends Aveda Jupiter and Bea and Evie Tanaka as they combat a new supernatural threat.

Lucy Valdez is many things: fight trainer/bodyguard to superheroines, fabulous vintage fashion plate, undisputed karaoke queen at local joint, The Gutter. She is also one of the toughest fighters in all of San Francisco without superpowers. So why can't she seem to confess her feelings to her longtime crush Rose Rorick, head of the San Francisco Police Department's Demon Unit?

Well.... actually, she knows why. She's afraid Rose won't like the real Lucy, the Lucy underneath all the fabulous bravado. (She is still fabulous underneath that bravado--just in a different way.)

When a mysterious new karaoke star rises up at The Gutter and eclipses her, Lucy finds her confidence further shaken--and when strange, seemingly supernatural happenings threaten both this new star and The Gutter's very existence, she must rise to the challenge and investigate alongside Rose. Will Lucy be able to vanquish the demonic threat to her beloved karaoke haven, confess her true feelings to Rose, and reclaim her karaoke throne?
