Patricia "Trish Trash" Nupindju is a talented young hoverderby player on Mars 200 years in the future. Trish wants desperately to go pro because it seems like the only way to escape a future of poverty and hard labor on her family's moisture farm in Candor Chasma. But even if she could make the team, she's too young to get a contract, and her family is going broke faster than her escape velocity.
