Summary from Goodreads:
Ava, a teenage girl living aboard the male-dominated, conservative deep space merchant ship Parastrata, faces betrayal, banishment, and death. Taking her fate into her own hands, she flees to the Gyre, a floating continent of garbage and scrap in the Pacific Ocean.
This is a sweeping and harrowing novel about a girl who can't read or write or even withstand the forces of gravity. What choices will she make? How will she build a future on an earth ravaged by climate change?
