The Secret Supers are bored out of their minds during summer vacation until they go to Space Camp. They learn all about the space program, try out moon gravity and zero-g simulations, and practice docking with the International Space Station. But that's the easy part. The villains they defeated in the past are back with a diabolical plot that renders the middle schoolers' superpowers ineffective. Jeremy, Aubrey, Dan, and Kayla face the biggest challenge of their lives. Even if they escape the villains' clutches, will they survive?
