The memoir, to be released through Transworld Publishers, will chart the journey of Harry Judd, Dougie Poynter, Danny Jones and Tom Fletcher from their early days sharing a house in Finchley to becoming the youngest band ever to reach number one with their debut album.
The book is promised to be "a frank, funny and original insight into the lives of one of the UK's best-loved bands", through which readers "will get to know the men behind McFly in a way they never thought they would".
A release from Transworld continues: "It will include surprising tales of growing up in the limelight and the euphoric highs and desperate lows along the way.
"But, more than that, it will shine a light on what it takes to make it to the top and stay there for nine years, all told in their unique and inimitable style."
Further details, including the book's title, publication date and cover art, will be released shortly.
McFly are scheduled to begin their 30-date 'Keep Calm and Play Louder' UK tour in Sheffield on March 18.
