What would you do if you and your best friend were suddenly given super powers on the last day of school? This is the question that 10 year olds Ana and Sallie have to answer, as they learn what it means to be heroes and classmates, and possibly save the world. On the last day of school, Ana and Sallie are suddenly given every kid's dream, the ability to run fast, turn invisible, talk to animals, and change shape. But this is just the beginning of what they can do. They can also clean polluted water, create 'green' power for cars and buildings, and even stop wars from being fought. It means they will have a very, very, very interesting summer, because the world definitely needs two 10-year old super heroes. Written by two eight year old twin sisters, "This Summer I Plan to Rule the World" is the first of a four part series of novels on the adventures of Ana, Sallie, and their friends.
