The current Cardiff chief had over six years as Leeds chairman before he quit the club's board in March 2003.
This will be the first time he has given a definitive account of the period that he would later describe as 'living the dream' as Leeds tried to break into European football's elite before their spectacular decline.
The book's synopsis says: "United We Fall" is the unique story of life inside football, told from behind-the-scenes of one of Britain's most legendary clubs - Leeds United.
"It is also the true story of the childhood fan who became chairman of his Premiership team. Peter Ridsdale, one of the game's most controversial and colourful figures, oversaw the most dramatic and talked-about period in Leeds United's history.
"In this compelling account, he writes about how the dream spectacularly unravelled when the club went into financial meltdown."
