TORONTO - A new Conrad Black memoir described as being "unflinchingly revealing" is expected to hit shelves in a few months.

McClelland and Stewart plans to publish "A Matter of Principle" sometime this fall.

It recounts Black's life from 1993 to 2011, including his time in prison.

McClelland and Stewart says it includes "candid" reflections on his marriage and close friendships.

Last week, Black was ordered to serve another 13 months behind bars for defrauding investors.

He was sentenced to 42 months in jail, minus the 29 months he's already served.
