Bestselling Camilla Isley returns with this gorgeously funny enemies-to-lovers rom com, perfect for fans of Sarah Adams, Lynn Painter and Jo Watson. She's a self-made fitness sensation. He's a billionaire mogul. They're sworn enemies and rivals... aren't they? 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. He might be one of the biggest names in the fitness world and set women’s pulses soaring more than a grueling HIIT workout, but he grew up in a billionaire dynasty and had everything handed to him – or so Blake thinks. 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?
