Tress from the Emerald Sea (with color cut) UA - Brandon Sanderson

Tress lives on an island in the middle of the sea. She has a habit of drinking salted tea from cups with history hidden in the cracks and chips. Tress also loves people. And she doesn't get upset if they talk a lot and sometimes lie unkindly, like her friend Charlie. But one day Charlie leaves the island because he has to marry a princess. Not by choice, but for political reasons. However, later it turns out that a disaster has happened. No one cares that Charlie might die. Everyone except Tress. But is the girl ready to leave her quiet life and go on a dangerous sea voyage, where every drop of water is a deadly threat?
