We loved this series. There's a fourth book out, that we haven't read yet, but it's on the TBR pile...
The first book reads like watching my son play Forza but with hot rods on the moon!
Right off the shuttle, the main character Benny and the motley cast of teen winners of Elija West's Scholarship for Courage, Ambition and Brains are saving each other -- and eventually Earth. Benny drives a 4-wheeler souped up for moon conditions to rescue Jazz, whose space runner vehicle crashes, and the Taj space resort is bombarded by alien asteroids.
The scholarship winners work together as a team led by a reluctant Benny to fend off an attack by the Alpha Maraudi (a play on the word marauder, perhaps?), who want to take over Earth and resettle it for their own people.
The second book picks up where the first left off, and again the scholarship winners have to fend off another attack with their brilliance, courage and ...yeah, there's some ambition in there, too. The Alpha Maraudi just keep coming, and unlike other books, which end when the threat is vanquished, Benny is still trying to fenagle a way humans and Alpha Maraudi can share Earth, while saving the most brilliant man alive, Elijah West.
Benny manages to convince a new Alpha Maraudi commander that humans are just like them. It doesn't hurt that she's got a little kiddo she's caring for on her invasion ship and carries around his ball in her tentacles. I won't spoil the ending, but you already know there's a fourth book, so I can tell you, the Alpha Mauradi still have a Commander deep in space, bent on annihilating the human race...
