Kobo and ECW Press say they've partnered to co-publish "Jian Ghomeshi — Secret Life."
Kobo says the book will reveal details and background about Ghomeshi and explore how he came to be fired as host of CBC Radio's "Q."
Ghomeshi is charged with seven counts of sexual assault and one of overcoming resistance by choking, but his lawyer has said he will plead not guilty to all charges.
Kobo and ECW Press say Donovan, who has covered the story for the Star, has interviewed a number of women and former colleagues from Ghomeshi's past.
Kobo will offer the book digitally while ECW Press will put out the print version to the North American marketplace.
Kobo vice president Pieter Swinkels says the book is "a thought-provoking story that forces us to look again at social, cultural and gender roles."
