Nocean: Atari and Tika (Nocean #1)

Ice melting has caused the oceans to swallow up vast swaths of the Earth. The ocean itself has radically changed and is now called the Nocean. The European continent's borders and coastlines have transformed; new cities have appeared where others have changed, and some have been abandoned for many years. A new form of government, called Systema, runs society along with the large corporations that support it. A neo-liberal dictatorship rejects those it no longer considers citizens. Amidst it all, two young orphan girls become modern-day Robin Hoods, helping the most needy – those whose voices have been repressed by the system.
