Worthy by Stella Moore

Handling bossy, demanding millionaires is just a regular Tuesday for Katherine Callahan, one of the most in-demand financial planners on the East Coast. Austin Barrick may be baseball’s biggest star, but she figures there’s not much difference between him and the rest of her clients.
That is, until he walks into her office, flashes his million-dollar smile, and asks her to dinner. Before they even leave her office, Kit discovers a thrilling dominance beneath Austin’s easygoing charm, and finds herself thrust into a dark, fascinating world of pleasure and pain.
But in a society that values beauty above all else, she’s learned one simple, brutal truth: Fat girls don’t deserve happily ever after. Can Austin’s sweet, steady dominance help her embrace a life she’s only dreamed of? Or will she let a culture of shame keep her in the shadows?
