In his bestselling memoir Waypoints: My Scottish Journey, Outlander star Sam Heughan offers a candid and often emotional look at the personal milestones that shaped him — from a difficult family history to the unexpected journey that turned him into Jamie Fraser, and the deep bond he shares with co-star Caitríona Balfe.

The book interweaves Heughan’s account of hiking Scotland’s 96-mile West Highland Way (culminating in a climb of Ben Nevis) with reflections on his childhood, career struggles, and the relationships that defined him. Raised by a single mother after his father left when he was young, Heughan writes movingly about her encouragement of his creativity and the confidence he found on stage as a shy child. He also confronts the complicated reappearance of his father later in life, including a difficult visit in Canada as the older man was dying.

Heughan does not shy away from the lean years before Outlander. He recounts the frustration of life as a struggling actor in his early thirties — including a memorable low point in Los Angeles involving a Stetson hat, an empty bank account, and tears on the Hollywood Walk of Fame — and the moment everything changed with a phone call: “You’re Jamie Fraser.”

A major focus of the memoir is his relationship with Caitríona Balfe. Heughan describes their first chemistry read as electric; the pair “tore chunks out of each other” in an intense scene and immediately sensed they had brought Jamie and Claire to life. From that day, he says, they instinctively protected each other. More than a decade later, he still calls her one of his best friends, a trusted confidante, and “the MVP of the Outlander team.”

“From when we started, she’s one of my best friends,” Heughan has said. “We’ve grown up together… from the beginning where we knew nothing really, to now where we’re producers on the show.” He praises her generosity, sharp humor, strength, and collaborative spirit on set. Balfe has returned the affection, describing him as a “gentle soul” who creates an easy, supportive environment and makes her feel like family.

Waypoints also touches on the darker side of sudden fame that both actors navigated, while celebrating the positive force of the Outlander fandom — including the charitable work inspired by the show, such as Heughan’s My Peak Challenge.

Honest, self-deprecating, and full of Scottish weather, the memoir marks Heughan’s third New York Times bestseller. It is less a straightforward celebrity autobiography than a reflective journey through the personal “waypoints” that brought him to where he is today: an actor, producer, author, and man still closely tied to the people and landscapes that made him.
