The rapper's life story will tell all about his difficult childhood and "violent and disruptive" teenage years.
Dizzee told the Evening Standard that speaking to his ghostwriter was like "a therapy session".
"I ain't had no therapy sessions before...but everyone's got secrets and I've got more than plenty," he told the newspaper.
The 25-year-old from Bow promises a no-holds-barred account of his eventful life. His story will talk about losing his father when he was a child, and his "difficult" teenage years, in which he was expelled from four schools, before he "cleared out the nonsense" to focus on his career.
He'll also talk about his transformation from pirate DJ Dylan Kwabena Mills into Mercury Prize-winning rapper Dizzee Rascal, and the traumatic incident when he was stabbed in Cyprus during the week his debut album, 'Boy In Da Corner', was released in 2003.
For Dizzee fans concerned that the rapper is turning his back on his art in favour of writing books, the 'Dirtee Disco' star promises that his music comes first: "I'll probably get the [fifth] album out [before the book]."
