There are many miles from the business school and basketball court at the University of Southern California to 50 million viewers for the final episode of a TV show called Magnum P.I. Tom Selleck has lived every one of those miles in his own iconoclastic and joyful way. Frank, funny and open-hearted, You Never Know is an intimate memoir from a beloved actor, the story of a remarkable life and thoroughly accidental career.

Journey to the top in Hollywood, learn of his mistakes and his well-earned success. Selleck clears up an armload of misconceptions and shares never-told stories. His rambunctious California childhood.

His clueless arrival as a good-looking college jock in Hollywood (from the Dating Game to the Fox New Talent Program to co-starring with Mae West). What it was like to emerge as a mega-star in his mid-thirties and remain so for decades to come, an actor whose ease on screen connected with audiences worldwide, while redefining the cliches of manhood.In You Never Know, Selleck recounts his personal friendships with a vivid army of A-listers, everyone from Frank Sinatra to Carol Burnett to Sam Elliott, paying special tribute to his mentor James Garner of The Rockford Files, who believed, like Selleck, that TV protagonists are far more interesting when they have rough edges. He tips his hat to the American western and the scruffy band of actors, directors and other ruffians who helped define that classic genre, where Selleck has repeatedly found a happy home.

Magnum fans will be fascinated to learn how Selleck put his career on the line to make Thomas Magnum a more imperfect hero and explains why he walked away from a show that could easily have gone on for years longer.Hollywood is never easy, even for stars who make it look that way. Selleck explains how he's struggled to balance his personal and professional lives, frequently adjusting his career to protect his family's privacy and normalcy. His journey offers a truly fresh perspective on a changing industry and a changing world.

Beneath all the charm, talent, and self-deprecating humor, this memoir reveals an American icon who reached remarkable heights through authenticity.
