Jide and Petra are just two normal kids until they are selected to leave Earth and join their new alien classmates on an intergalactic research mission to Mars. Too bad Jide has no idea how she ended up in the program, seeing as the closest she wants to get to space is being a sci-fi writer. Petra, on the other hand, is the brains of the mission, but his helicopter parents make it clear he hasn't left their gravitational pull behind quite yet.
