The book by Stephanie Madoff Mack - "The End of Normal: A Wife's Anguish, A Widow's New Life" - goes on sale Thursday.
The wife of Mark Madoff writes that he survived a suicide attempt four months before he killed himself on Dec. 11, 2010 - the second anniversary of his father's arrest.
The book vilifies her father-in-law "Bernie" while calling her husband an innocent bystander and "hero" for turning him in.
The elder Madoff is serving a 150-year prison term for orchestrating a massive Ponzi scheme that wiped out thousands of clients. His two sons and brothers were executives at the Madoff firm but haven't been charged with any crimes.
