He's remained in the spotlight ever since, and here he talks in depth for the first time about his childhood, his astonishing experiences as a young man and Christian growing up in one of the biggest bands in the world, his shock and frustration at the band's eventual dissolution, and his subsequent career, including his four months in Russia, training to become a cosmonaut.

He also frankly discusses life as a gay man -- his first same-sex relationship at twenty-one, his struggle to keep his sexuality hidden from *NSYNC's fans in case it jeopardized the band's success, and the true circumstances that led to his decision to publicly come out at the age of twenty-seven.

Full of fascinating behind-the-scenes lore and revealing insights from a pop star who, until now, has been notoriously private, Out of Sync is the book that millions of fans have been waiting for.
