Twelve-year-old Calliope "Calli" Canderine just wanted a normal life-photography, archery, and hanging out with her best friends Kay and Chris. But when her sorceress mother tries one forbidden spell too many, Calli accidentally summons Hades himself... who also happens to be her grandfather.In a flash of godly rage, Hades strips Calli's mom of her magic forever and unleashes the Dark Curse-a creeping shadow that threatens to swallow the mortal world. With her mother powerless, her dead astronaut father still out of reach, and monsters now hunting her, Calli discovers she's inherited more power than she ever wanted.Teaming up with her loyal (and slightly chaotic) friends, Calli must journey across modern cities and ancient ruins, face family secrets in the depths of the Underworld, and confront the King of the Dead himself. Because if the Dark Curse isn't stopped, everyone she loves will pay the price-including the grandfather who started it all.A fast-paced, funny, and heart-filled middle-grade adventure blending Greek mythology with friendship, grief, and finding your own kind of magic.
