Renowned feminist Gloria Steinem has put out her new book "My Life on the Road" and she has a special person to dedicate it to -- Dr. John Sharpe -- the doctor who performed abortion to a younger Steinem half a century ago and the person to whom the 81-year-old made a promise to.

"You must promise me two things. First, you will not tell anyone my name. Second, you will do what you want to do with your life," Steinem wrote in the first pages of her memoir as she quoted the late Dr. Sharpe.

Steinem revealed in "My Life on the Road" that Sharpe agreed to abort the baby of the then 22-year-old back in 1957, a time when abortion was illegal in England. She thanked Sharpe for taking the "considerable risk of referring for an abortion a twenty-two-year-old American on her way to India."

Up until now, Steinem, who has always been exceptionally vocal about her support on abortion, continuously works to fulfill her second promise to the late physician. In the book, she further wrote "I've done the best I could with my life. This book is for you."

Steinem has asserted her stance on abortion on multiple occasions. Back in 2013, President Barack Obama awarded Steinem the Presidential Medal of Freedom in recognition to her enduring and unfaltering abortion activism.

During a chat with Life News, the "Ms." magazine founder stated that "Every child has a right to be born loved and wanted. And a woman who decides that this is not the moment when she can provide that for a child is making, to me, a profoundly moral decision."

In "My Life on the Road," Steinem recounted her experiences, big and small, during her travels, as well as the people she had the pleasure of meeting as she went about the journey. The book is now the Women in History bestseller on Amazon and the rave reviews continue to surge.

Penguin Random House billed the book as a "moving, funny, and profound story of Gloria's growth and also the growth of a revolutionary movement for equality -- and the story of how surprising encounters on the road shaped both."

The tome also promised to take readers to a ride, with Steinem from her "itinerant childhood," to her first exposure to social activism in India and all the way to her becoming of journalist, each story demonstrating Steinem's tenacity to change the world one road trip at a time.
