Fringe Contender by E.M. Lindsey

Reeling from his divorce, Rhys Anderson is trying to find his footing again. Having just returned from a long trip, he finds the lives of the people he cares about most in total disarray. In the midst of trying to help his brother’s ex deal with a blackmailer, a man enters his office for a consultation and divulges a secret of his own—he, too, is being targeted by the blackmailer. When Rhys suggests that Trevor Greene go public, Trevor reveals a secret which would prevent him from coming forward, and he quickly leaves.
Not sure Rhys will ever see Trevor again, the mysterious man stays on his mind until one night he runs into him and sees just how badly the blackmail has devastated Trevor’s life. Rhys immediately steps in and insists he be allowed to help. He expects to get to the bottom of things. What he doesn’t expect is to find a reason to love again. If only things weren’t so complicated. Will Rhys and Trevor be able to find their way together, or will the danger Trevor’s in keep them apart?
