Meet Jo. . . the brown-eyed, brunette half of T. S. Livingston! Hailing from Providence, Rhode Island, she’s the more thoughtful and cautious of the twins, but she shares her sister’s imagination, sense of humor, and love of mysteries. In between all their madcap antics–and perhaps because of them–Maddie and Jo are closer to solving the Mystery at Madame Molineaux’s than anyone–even the professors!
