The book is about a girl on a snow planet. She boxes for funds and owns tiny robots that she coded herself. I believe she had a wristband that helped her code if I'm not mistaken?
A ship crashes on her planet near her house, which is away from all the other people. The robots help her work in the mines by her house. She ends up having to go on a trip with the boy in the ship.
She finds out she's a princess and that her kingdom is corrupt. The title had something to do with snow.
