When the first puck dropped in the Professional Women's Hockey League in January 2024, it had been a long time coming. Women have been playing hockey since at least 1890 and playing professionally for decades. But until 2024, even the highest-level female players had never been compensated as professionals: some paid for their own gear and worked second jobs, earning a pittance, if anything, from their chosen profession. In Breakaway, Karissa Donkin tells the story of the players' efforts to create the PWHL, long before the first full season in 2024. Following the unnamed 2024 Montreal PWHL team, with some of the best players in the sport, like Marie-Philip Poulin and Erin Ambrose, Donkin takes readers through the League's founding, the draft process, the practices, and the dramatic arc of the first season. Defying all expectations, with larger crowds and higher revenues than anticipated, this first season was a gamechanger for professional women's sports leagues.
