Submarines

Australia. 2151. Fifteen-year-old Saha Leeds decides to spend her summer vacation before her final year of school in the ocean depths. Her father, a submariner, a man of the sea, lives somewhere down there. It is thanks to his genes that she can breathe underwater, which means she can embark on a solo journey along the Green Continent. But the civilization left on shore won't let Saha go: yachts and ships speed overhead, fishing nets, methane mines, and power plants are encountered time and again, and on the seabed, cables, pipes, and endless trash are visible. Moreover, the heads of some corporations declare a hunt for underwater dwellers. And only one of the submariner tribes is not afraid to fight back. Now Saha understands that she is not just a guest in the underwater kingdom—she is a Mediator who must unite the people of the water and the people of the air. Can the heroine stop the war?
