"Kat is a warrior, both on the track and off it. This book is a stunning testimony to the power of believing in yourself" - SIR CHRIS HOY

"An extraordinary story of resilience and determination, from an incredible athlete" - DAME JESSICA ENNIS-HILL

The inspirational and powerful memoir from double world heptathlon champion and Team GB Olympian Katarina Johnson-Thompson.

Katarina Johnson-Thompson has never had it easy. Born a child of two worlds - her mum's working-class Liverpool, and her dad's idyllic Bahamas - she was never supposed to be a world champion. Her early childhood wasn't easy. She was raised by a single mother, and at times it was a struggle for her to keep up with other athletes who had more funding around them. But she persevered.

Now, in her intimate, heartfelt autobiography, she tells her story as she never has before. She opens up about the pressures of representing Britain at the London Olympics while just sixteen years of age, and about her complex relationship with mentor-turned-rival Jessica Ennis-Hill. Unbroken is a rare insight into the inner workings of a champion's mind: the rigorous discipline, the undying passion for sport, and the unshakable belief in one's self despite the odds.

Johnson-Thompson's journey has been a remarkable one. Her upbringing and her career, both rich with challenges overcome and dreams pursued with relentless determination, serve as a powerful reminder that the human spirit is capable of extraordinary feats. But this is more than a story of triumph-against-the-odds. It's a testament to the sweat, tears and laughter that pave the road to success, and to the unyielding spirit of a true champion.
