E.M. Rensing

On a world where everyone looks to the depths, she has always looked to the stars.Unara has never wanted what others want. On a world where every day is a fight for survival, she dreams of peace in the silence of space. But being born under the waves comes with a price; nobody leaves Thalassa Prime. Not that Unara's going to let that stop her. For soon, Trader Houses from across the galaxy will be descending to the sun-scorched surface of Thalassa Prime for a once-in-a-lifetime event, ready to fill their holds with all the riches of the world-sea.
And when they leave, Unara is going with them. But dark forces are stirring in the ocean, and the Trader Houses bring their own conflicts with them. When old grudges spill out into open rebellion, Unara is forced to choose between her own future or saving the world she wants to leave behind.
