Jeannie and Anne-Marie Hilton, aged 21 and 19 respectively, are set to publish their book in October.
Hilton was convicted in March 2001 of sexually assaulting two teenaged girls. The former WBC super-middleweight champion was sentenced to seven years behind bars.
At the time of the trial, the girls were not identified, but the awful truth is out. Anna-Maria Gatti, Hilton's ex-wife and sister of WBC light-welterweight champion Arturo, said writing the book was a form of therapy for her daughters. She hasn't read the book and doesn't know if she will.
Both daughters now live in the United States, one near Chicago, and the other in Florida.
Jeannie Hilton has criticized the Canadian justice system for not imposing a more severe sentence on her father.
