Amy’s Guardian by Regan Black

Beau Brennan’s new job as the sheriff of Heartbreak Key is a far cry from the big cities he’s worked in his whole career. But he likes the quiet and solitude of island life—it’s a chance to heal from losing his law enforcement partner.
Alone is the way Beau operates best.
He definitely wasn’t expecting someone like Amy Young—here on the the island for treasure hunting of all things. In her mid-40s, downright beautiful, and finally out from under the thumb of her narcissist ex-husband, her big personality and even bigger smiles are drawing him in.
And Beau doesn’t even think he wants to resist. Especially when he finds out Amy’s smiles hide insecurities about herself he’s more than willing to prove wrong.
And when treasure hunting fun takes a deadly turn, this gruff sheriff will stop at nothing to keep Amy safe. And make her his.
She thinks the best years of her life are already gone? Hell no. Because it’s never too late for love.
