Cosmic Cadets (Book One): Contact!

"Humanity has gone to the stars, and the ESS Khonsu and its crew are leading the charge to explore the galaxy. As the son of the ship's captain, Jimmil might not always live up to his mom's expectations ... but right now he and his friends might be the galaxy's only hope. After they're stranded on a strange alien planet, they'll have to do what their parents couldn't: explore the surface, discover the secrets of the terrifying race that lives there, and try to prevent a full-scale war! Working together, these Cadets will discover that sometimes being a hero means learning to see new perspectives, and sometimes bravery means admitting when you're wrong."--
