The Bull's Daughter Writing Book About Mafia Life

A man who needs no introduction.

Karen Gravano, the daughter of infamous mob turncoat Sammy (The Bull) Gravano, has inked a book deal to pen a tell-all about her life growing up in a Mafia family, according to the New York Post.

The deal with St. Martin's Press is for six figures, according to the report.

Karen, 38, will write about growing up in a Mafia enclave on Staten Island as the daughter of one of the mob's "most feared executioners," including how her life changed after Sammy testified and entered the witness protection program, and "went to prison in order to protect Karen and her brother," St. Martin's told the Post. [Is that before or after they were all selling the E? --Edit. note.]

Sammy Gravano received leniency for testifying against mob boss John Gotti: He served five years in prison before moving to Arizona in 1995 under the federal witness protection program.

In 2000, the elder Gravano was busted again for running a multimillion-dollar ecstasy ring near Phoenix and sentenced to 19 years in prison.

Karen Gravano pleaded guilty to charges related to her father's drugs operation and was sentenced to probation.
