Today she's the world-famous survivor of a Taliban assassination attempt, an activist for girls' education - and a contender to win the Nobel Peace Prize later this week.
It's easy to forget she is still a teenager, and now a long way from home.
The memoir "I Am Malala" goes some way toward redressing that balance. Published around the world on Tuesday, the book reveals a girl who likes "Ugly Betty" and the cooking show "Masterchef," worries about her clothes and her hair, but also has an iron determination that comes from experience beyond her 16 years.
The book, written with the British journalist Christina Lamb, recounts Malala's life before and after the moment on Oct. 9, 2012, when a gunman boarded a school bus full of girls in Pakistan's Swat Valley and asked "Who is Malala?" Then he shot her in the head.
The shooting is described briefly but vividly in the book, which is briskly written but full of arresting detail. "The air smelt of diesel, bread and kebab mixed with the stink from the stream where people still dumped their rubbish," Malala remembers. One of her friends tells her later that the gunman's hand shook as he fired.
Around that pivotal event, the book weaves Malala's life story into the broader tale of her home region of Swat, a remote, mountainous region near the Afghan border. She says it is "the most beautiful place in the world," but it's also a crossroads traversed for millennia by armies and invaders, from Alexander the Great to Winston Churchill.
Into this valley, in the years after 9/11 and the U.S.-led invasion of Afghanistan, came the Islamic fundamentalist Taliban. The book describes their arrival - preaching against girls' education, shutting down DVD sellers and barber shops and displaying the bodies of people they've executed. They blew up the region's ancient Buddha statues, and then they began blowing up schools.
"They destroyed everything old and brought nothing new," Malala writes.
Malala considers herself a believing Muslim and a proud member of the Pashtun ethnic group, but recounts how from an early age she questioned her culture's attitude toward women.
"When I was born, people in our village commiserated with my mother and nobody congratulated my father," she writes.
Her father felt differently. The book recounts her debt to Ziauddin Yousafzai, an educator who founded the school Malala attended and kept it open to girls in the face of pressure and threats. He passed on to his daughter a hunger for knowledge and a questioning spirit.
At 11, she began giving TV interviews in Pakistan about girls' education. In 2009, she started writing a blog for the BBC Urdu service under a pseudonym.
She soon became well known within Pakistan - and therefore a potential Taliban target. But she was reassured by the thought: "Even the Taliban don't kill children."
That optimism proved misplaced, but - miraculously, it seemed to many - Malala survived the shooting.
The final part of the book describes Malala's life from the moment she regained consciousness in a British hospital, where she had been flown for specialist treatment, with the thought: "Thank God I'm not dead."
She undergoes intense pain and multiple surgeries. In the hospital, Malala asks why her abdomen appears hard and swollen. It is the top of her skull, removed to alleviate pressure and stored there until it could be reattached.
There are other striking, surprising details. Malaala's favorite actress is Angelina Jolie. She loves the TV show "Ugly Betty," whose central character works at a fashion magazine; Malala dreams "of one day going to New York and working on a magazine like her."
In the hospital she enjoys the "Shrek" movies, but is shocked by the scene in "Bend it Like Beckham" when the female soccer players take off their jerseys to reveal sports bras.
She reads "The Wonderful Wizard of Oz" - sent to her by former British Prime Minister Gordon Brown - and identifies with Dorothy, trying to get home.
Malala goes to school in England now, and lives with her family in a house behind a big gate in the city of Birmingham. It reminds her a bit of being under house arrest.
The Malala Fund set up in her name campaigns for girls' education around the world. She has received multiple awards and addressed the United Nations on her 16th birthday. Later this month she is due to meet Queen Elizabeth II at Buckingham Palace.
She remains determined to return to Pakistan one day and enter politics. And she says the Taliban's attempt to silence her has backfired spectacularly.
"When I was shot they thought the people would be silenced, they thought that no one would talk," she told the BBC in a recent interview.
"I think they might be repenting why they shot Malala."
