Crash landing - Scott Seegert

Middle school in space! An alien dog! A mad scientist! Hundreds of
illustrations! James Patterson presents a hilarious space adventure
featuring an average human kid getting into a universe of trouble.
Kelvin is the new kid at Sci-Fi Junior High, a floating space station
filled with alien kids from across the universe. And he arrived
just in time for the annual school dance: The Galactic Get Down!
Kelvin is desperate to take luminous Luna (her species literally
glows), but now that his secret about not being a Mega Supergenius
is out, Kelvin doesn't have a shot. He has to think of a way
to become super cool so everyone forgets he lied about his average
intelligence...
Cue mad scientist Erik Failenheimer's escape from his asteroid prison
and a battle to save Sci-Fi Junior High from imminent doom.
Let's dance!
