Stephanie Madoff Mack, daughter-in-law to disgraced Ponzi schemer Bernie Madoff and widow to his son, Mark Madoff, slammed her father-in-law in her book and called her late husband a hero for turning him in.

The End of Normal: A Wife's Anguish, A Widow's New Life was released on Thursday.

Madoff Mack painted a picture of a father-in-law who had a rude personality and made sleazy comments when she gained weight during her pregnancy with her first child, his grandchild.

His narcissism might have been laughable if it had not been so dangerous, she wrote, MSNBC.com reported.

There was also the matter of being asked to sign a pre-nuptial agreement before marrying Mark.  

Bernie had rendered the most beautiful moment of my life so far into something cold and calculating, she wrote, the UK's Daily Mail reported.

Madoff Mack wrote of how her father-in-law broke the news of the failed Ponzi scheme to his sons.

Bernie betrayed no emotion or remorse, calmly delivering his bombshell with the cool demeanor of an anchorman reading a wire report on the evening news, she wrote, The New York Post reported. When he was done, he began to cry.

As for her mother-in-law, Ruth, Madoff Mack wrote that she could take you down like a sniper by making unfiltered comments, the Daily Mail reported.

Madoff Mack described Ruth as a superficial woman who was concerned with her looks and would pour salt over her unfinished meals to avoid overeating.

She also revealed that her late husband was planning on writing a book about his father's downfall and his own experience.

Her husband, she wrote, had previously attempted suicide in 2009.

When he did commit suicide in 2010, she thought I will never forgive you, Mark Madoff, MSNBC.com reported.
