A few years ago I read a really good Sci-Fi I want to find again. I know it started with The, and has a purple cover.

_Spoilers_ A group gets kicked out of space piloting school and on the shuttle back the space station gets attacked so the leave earth and can't go back according to some rule. But they go to a few separate colonies and find the main characters brother and learn they have to stop a group called earth first from destroying the colonies. By the end they have a ship called the kick.
The only character name I can remember is Case, a smart girl. And maybe one called Malcom. That's all the info I have thank you.
