Tad and Sara are now the parents of Olimpia (Oli), an adorable and intrepid two-year-old girl. And Momia isn’t taking it well at all that she’s no longer the center of attention. While on vacation in London, Sara follows the trail to a unique object: the magic lamp from *One Thousand and One Nights*. And Momia, consumed by jealousy, makes a wish: to travel back in time to when she was young and everyone loved her. Tadeo and Sara must join forces to prevent Momia from changing the course of history and bring the group—including Jeff, Belzoni, and Ramona—back home to their own time. This new adventure will take them across the Atlantic Ocean from Peru to Greece, and from there deep into the Middle East, all the way to the very cave of Ali Baba and the Forty Thieves.
