The Catcher by Kate Raven

"What it means, Em, is that you’re going to do what I want, whenever I want, or I’ll tell everyone your dirty little secret." Art therapist Emrys Finnegan thought she'd left the fast-paced world of Public Relations behind when her old boss calls to offer her one last job. And it pays the kind of money that could change Emrys' life forever. There's only one catch. She'd be working for disgraced major league baseball superstar Tanner Courtenay. And he’s a legendary PR nightmare, a violent and unstable athlete with a rap sheet a mile long. Emrys has no choice but to grit her teeth and put up with Tanner's contemptuous treatment and malicious cruelty. But when one day he goes too far, everything changes. Suddenly, Tanner would do anything to get Emrys to stay with him. And with his wealth and ruthlessness, it's only a matter of time before he gets what he wants… This is a fast-paced dark baseball romance with bullying, blackmail, obsession, breeding, groveling, and a HEA.
