Depths

I'm dying, and I need a human sacrifice in order to survive.
To maintain my place as Queen of Okeanos, I need someone to quite literally take my broken heart into their body.
So... I'm hosting a tournament to find a willing puppet-someone who will let me pull their strings.
But who should I choose?
The sweet, funny courtier?
The seductive stranger?
The rebel who hates me as much as his next breath?
Or someone more loyal, closer, more true?
The options weigh me down as all around me, threats emerge. Attacks. Someone doesn't want me to rule the depths.
I need to change the tides to keep from being dragged under, but can I survive long enough to choose my own fate?
This is a slow burn, slow build reverse harem romance intended for mature listeners. There is a bit of a chasm (sea kingdom talk for cliff) at the end of book one. You've been warned.
