Black Cat Social Club, bd

When Hazel sells her soul to a demon for more magical power, Alice steps in and assumes the debt herself. But the more demon-power Alice uses, the more energy is generated for a
diabolical project, hatched by a group of really obnoxious corporate demons to turn the world into a smoldering hellscape. The only way to undo it is with the most powerful song ever, a real Killer Song—and it turns out Maggie may have written it! If the band can get a chance to play it, it could either end this Armageddon, or end them all!
