Mermaid's Vengence by JC Brown:
 
A siren seeking revenge. A man obsessed. A love born from the dark sea.

Scarlett

Everything changed the moment Scarlett’s ex killed her. But in death, the God of the Sea gave her life. Now, she spends her days enacting her revenge on the man who murdered her.

Until Scarlett discovers a drowning man in the sea…one she can’t help but feel drawn to. But saving Tristan comes with more consequences than either of them are ready for.

Can Scarlett let go of her vengeance against the man who took her life? Or will her heart sink along with the chance to find happiness once more?

Tristan

For as long as Tristan can remember, he’s been fascinated with the ocean. It’s why he became an oceanographer in the first place. When things go sideways while trying to secure the funding Tristan’s company needs to save the seas, he discovers the truth about what lies beneath the waves.

And now that he’s seen her— his mermaid—he knows there isn’t anything that will stop him from finding her again and making her his.

Even if it kills him.

Can Tristan convince his siren to give up her vengeful song and set herself free? Or will he become another casualty of the ocean’s most wicked predator in the process?
