13-year-old Emilia Harper is a kid-genius with a dream of going to Yale University and has made her own tech-repair company to help pay for it. When a mysterious woman appears to ask for help fixing her ancient computer, things go wrong. She finds herself stuck with her twin brother, Pedro, in an unfamiliar place. Will she selfishly go back home, or stay to help the people of this world? The fact that sheÕs the main character, a computer genius and the book is pretty long suggests that sheÕll probably stay.
