Intent to Kill by Amy Barnett

Five years after faking his death Adam Vandemilio returns to his organized crime driven hometown to enact his revenge, only to find the love of his life now engaged to the man who nearly murdered him.
Adam and Mercedes, lovers and partners in crime, almost had it all. Until a single encounter with Dorian Blake – head of the Blake Family Crime Empire – nearly ends Adam’s life and separates them for good.
Five years later, after faking his death, Adam Vandemilio returns to Ridge City, Florida, his tropical organized crime driven hometown to enact his revenge. But his friends and his city have moved on without him. And Mercedes? She’s now engaged to the man who nearly murdered him.
Setting off to reclaim what was taken from him, Adam must face deadly opponents, impossible challenges, and worst of all, his own failings if he wants to win back his friends, his empire and his girl.
There’s only one thing he knows for certain. Mercedes is his. He’ll win her back. Or kill trying.
