The Catch, Tides of Fortune Book 1. Tides of Fortune, #1

When a struggling fisherman catches the impossible in his net, everything changes. Garrett Reed is three months behind on his dock fees and one bad day away from losing his boat-the last thing connecting him to his father's memory. The fish aren't biting, the debts keep piling up, and drowning feels inevitable. Then his net comes up with something that shouldn't exist. A mermaid. Moira is unlike anything Garrett's ever seen-beautiful, fierce, and trapped in his fishing net.
He cuts her free without thinking twice. What he doesn't expect is for her to come back. Or for her to start bringing him treasures from the deep ocean floor-shipwrecks full of salvage that could save him from financial ruin. But every gift comes with risk. Corporate salvage companies are asking questions. Her underwater family has rules about humans. And somehow, between the stolen moments on his boat and the secrets they're both keeping, Garrett finds himself falling for someone he can never really have.
She lives in a world he can't breathe in. He belongs to a life she can't be part of. Some boundaries aren't meant to be crossed. But when your heart chooses for you, logic doesn't stand a chance. The Catch is the first book in the Tides of Fortune series-six connected novels about love that defies every rule, relationships that bridge impossible worlds, and the courage it takes to fight for something everyone says can't work.
Perfect for readers who love paranormal romance with heart, working-class heroes who refuse to give up, and love stories that feel real even when they're wrapped in magic.
