Thirteen-year-old Lilla feels she is a bit different. She's quiet and shy and sometimes feels uncomfortable in the company of boys. She'd much rather spend time by herself drawing and daydreaming. This summer, while staying with her aunt in rural Italy, Lilla discovers a book of magic which reveals that she is a witch with special powers, the magic of 'Strega'.
But unbeknownst to her, an ancient witch, Stregamama, threatens to ruin more than just her summer. Lilla is soon faced with a choice that could change her life forever.
