Paralympic gold-medalist, world champion swimmer, ESPY winner, and NBC Sports commentator whose extraordinary story will give you the encouragement you need to rise up to meet any challenge you face in life.

On January 21, 2008, a routine medical procedure left Mallory paralyzed from her waist down. Less than two years later, Mallory had broken eight world records, and by the 2012 Paralympic Games, she held fifteen world records and thirty-four American records. Two years after that, a devastating fall severely damaged her left arm. But despite all of the hardships that Mallory faced, she was sure about one thing: she refused to give up.

After two reconstructive surgeries and extended rehab, she won two gold medals and a silver medal at the 2019 World Para Swimming Championships. And even better, she found confidence, independence, and persevering love. She even walked down the aisle on her wedding day against all odds.

Mallory's extraordinary resilience and uncompromising commitment to excellence are rooted in her resolve, her faith, and her sheer grit. In Limitless, Mallory shares the lessons she learned by pushing past every obstacle and expectation that stood in her way, teaching you how to:

• redefine your limits
• remember that healing is not chronological
• be willing to fail
• lean on your community
• embrace your comeback
• write your own ending

Mallory's story reminds us that we can handle whatever challenges, labels, or difficulties we face in life, and we can do it on our own terms. Because when we refuse to accept every boundary that hems us in--physical, emotional, or societal--we become limitless.
