My Wayfaring Billionaire

Colton Grimwood, the oldest brother of the billionaire family, rubbed the sea salt from his eyes, sure he was seeing things. A mermaid? Swimming in the lagoon of his inherited island?Impossible.
Colton had recently returned to his family's vacation spot in hopes of turning it into a financially sound investment. What he planned to do was sell the cursed island.

The sooner the better.

But then, after a nearly-drowning encounter with a shark named Murphy, then being rescued by the mermaid, who turns out to be the island's swim instructor, Colton finds himself caught in a net of longing for something he'd promised himself he'd never feel again: love.

My Wayfaring Billionaire is the third book in the Grimwood Legacy Series.
