Poseidon by Carly Spade

Oceanographer and professional gamer, Cordelia Bourne, has had an unexplained connection with water and aquatic life for as long as she could remember. With days spent taking photos underwater and nights spent streaming her live game play of video game Tides of Atlantis, even as an adult she surrounds herself with anything aquatic.
When she meets pro surfer, Simon Thalassa, her entire world begins to change. One look into his green eyes and she gets the sinking feeling that she’s met him before even though she knows she hasn’t.
But after a fateful day at sea, realizations pour in, and soon she’ll discover Simon is Poseidon, King of the Seas and she has a special connection to him.
