Of Oceans and Broken Princes by Erin Fae

Naria never expected her faery bond with Prince Arenn to cut so deeply. Plagued by dangerous nightmares and unwanted fantasies of her vicious faery prince, she stays hidden within the walls of King Lukas’s palace. But his palace can’t protect her forever – and neither can Lukas.
Especially not while he refuses to accept the divine power buried within him.
To save her growing kingdom, Naria ventures to the sun-kissed shores of Ryntook. But soon, merfolk emerge from the corals desperate to take Lukas with them, and when Prince Arenn finds her on a starlit beach, he vows to claim her for himself – by any means necessary.
Caught between an obsessive faery prince and a deadly merfolk king, Naria must decide: will she give in to Prince Arenn’s twisted desires, or sink into the vast ocean of King Lukas’s heart?

An ocean dangerous enough to drown them both…
