Driven to bring more attention to female stories of courage and endeavour, Louise Minchin pushes herself to the extreme and embarks on thrilling endurance adventures with trailblazing women. She freedives under the ice in the dark in Finland with Cath, the first woman to swim a mile in the Antarctic Circle; she cycles across Argentina with Mimi, one of the world's most famous female endurance runners; and she swims from Alcatraz with Anaya and Mitali, two young sisters who have braved the shark-infested waters over 70 times. With her natural empathy and sense of humour, Louise forms close bonds with 18 incredible women. She explores what drives them and how they find the resilience and determination to go on despite life's setbacks. Lizzie overcame a life-threatening illness and now paddleboards whilst cleaning up the planet with her community; Rhian set up a charity in the face of grief and fundraises through hikes; and Zee took up rugby alongside her busy nursing career and motherhood. Louise reminds us of the bravery inside us all, and how essential it is to celebrate women's achievements. Prepare to be touched and inspired by these fearless women.
