Tideborn King (Kings of the Abyss Book 2)

He was born to rule the deep.
Twenty years after the drowned queen saved a dying species, the hybrid prince Kai must claim his throne, and his crown demands a public mating.

Dr. Waverly Adams is the one human alive who can stop the new poison killing hybrid children. She is also the one human Kai cannot touch without the ancient blood-bond driving them both feral.

One trench collapse.
One unbreakable bond that floods them with each other’s rage, grief, and raw desire.

Enemies become captives.
Captives become co-conspirators.
Co-conspirators become murder spouses.

To save the children bleeding from the gills, Waverly must return to the surface. To keep the secret of Crystalhaven, Kai must follow, shifting to legs for the first time in years, pain searing through every bone.

Together they will infiltrate the corporation that poisoned the sea, pull a confession from the man who murdered her brother, and drag him into the dark where monsters wear crowns.

A dark, possessive, revenge-fueled mermaid romance featuring:
• feral hybrid merman king with glowing royal markings
• enemies-to-lovers forced proximity
• size-difference intensity
• public claiming and royal coronation
• revenge murder on the high seas
• a human scientist who becomes the queen the ocean feared

The ocean crowned its king.
The king crowned his queen.
And the trench finally learned what happens when fire meets gold.
