In PEOPLE's exclusive cover reveal of the four-time Olympic gold-medalist's book, Relentless Spirit: The Unconventional Raising of a Champion, due out on December 6, 2016, the athlete looks just as fierce and captivating as she does before a competition.
The family memoir tells the story of Franklin's journey to swimming superstardom and was written by Franklin, 20, and her parents, D.A. and Dick Franklin.
"This book isn't just about swimming. Yes, swimming is a big part of it, but it's ultimately a story about our family, the strong bond we share, and the decisions we've made as a family to get to where we are today," the eleven-time World Champion says. "It's very exciting to tell our story in our own words."
Franklin first captured the world's attention with her youthful joy (and exuberant tweets!) at the 2012 London Games, where she wowed viewers with a record-breaking performance in the 200-meter backstroke.
Her fitting nickname in London was, "Missy the Missile."

Franklin, who is training in Colorado for the 2016 Rio Games, has said it is her dream to become the most decorated female swimmer Olympian of all time.
I'm obviously not excited that Rio is in 6 months... This video did such an excellent job of capturing how much of a dork I am, which let me tell you, is really hard to fit into a five second clip! Can't believe I'll be chasing my dreams for a second Olympics so soon!! Incredibly thankful to be living my dream every day #RoadtoRio
After Rio, Franklin will return to University of California Berkeley to continue her studies in psychology.
