Thirteen-year-old Houston Williams is smart. Very smart. So no one is surprised when he earns a scholarship to attend a prestigious NASA space camp. At the training facility he immediately bonds with his new team, including a girl named Teal. He also clashes with a girl on a rival team named Ashley, who matches or beats him in every exercise. The three of them impress the directors so much they are invited to join a top-secret research project that studies how space travel affects people of different ages. But only two of them will actually be going into space. Houston will do whatever it takes to make sure he's picked.
