Ohre (Heaven's Edge #2). Heaven's Edge Novellas, #2

Ohre suppressed his wild nature while living on board Datura 3. Plucked from the bottom of the ocean as a boy, he struggled to learn the ways of the land dwellers. He never asked to live with the heaven-sailing miners. But when his adopted clan's ship is attacked, he must give into the instincts he long fought against. After fighting to keep Qeya and the Royal children, alive, he finds himself abandoned once more.
All Ohre wants is the kind of freedom a life in the sea can give. But he doesn't want to live it alone anymore. He wants the princess and if Qeya won't come willingly, he'll make her.
