Roopa Pai suspects she has alien blood, for two reasons. One, she loved history in school. And two, although an adult, she mostly reads children's books. Roopa has won a Children's Book Trust award for science writing. Among her published works are a four-book science series, Sister Sister (Pratham Books), and two girl-power books, Kaliyuga Sita and Mechanic Mumtaz (UNICEF). When she is not dreaming up plots for her stories, she goes on long solo bicycle rides, and takes children on history and nature walks in Bangalore. You can find her at www.roopapai.in.
