Princess Daisy has spent her whole life believing in one perfect certainty: when she turns eighteen, the Calling will show her the face of her soulmate - and it will be a merman, exactly as tradition demands. Instead, she dances through an entire ballroom of eligible princes and feels nothing at all.
Heartbroken and desperate, she flees to the surface - the one place every mermaid is taught never to look. There, drawn by nothing but reckless curiosity, she's captured by the crew of a pirate ship... and finds herself staring into the eyes of their captain. An exiled prince. A human.
Her soulmate.
Ryan never asked to fall for a mermaid pulled from his own net, and Daisy never imagined trading a crown beneath the waves for a stolen ship and a fight to reclaim one above them. But as an old kingdom's tyrant king refuses to yield his throne, and two worlds that have feared each other for centuries are forced to finally look one another in the eye, Daisy and Ryan will have to decide what they're willing to risk - a family, a legacy, and a love neither the sea nor the crown ever accounted for.
Some bonds aren't written in old prophecies. Some are simply written in the tide - and the tide always finds its way home.
