Blake Avery knows all about hard work. She’s gone from making videos in her teenage bedroom to founding a booming fitness business and opening a state-of-the-art Manhattan gym. Now she’s on the cusp of realizing her wildest dreams, and she’s not going to let anyone stand in her way. Certainly not man-of-the-hour Gabriel Mercer.

But when Blake publicly criticizes Gabriel, she sparks a feud that neither entrepreneur is willing to back down from. And in an industry that seems determined to keep pushing them together, can Blake hold on to her grudge? Or will she finally warm up to Gabriel’s charm?
