Amy Fisher Pens Autobiography

Amy Fisher (search), the former gun-toting teen who spent seven years in prison for shooting her lover's wife in the face, has an autobiography called "If I Knew Then..." due out in the fall.

Fisher, who turns 30 in two weeks, is now married and raising a young son in an undisclosed Long Island community, her co-author, Robbie Woliver, said Thursday.

Woliver is also the editor-in-chief of The Long Island Press, a free weekly that has featured Fisher as a columnist for the past several years.

Fisher was released from prison in 1999 after serving seven years for shooting Mary Jo Buttafuoco (search) in the head during a confrontation outside Buttafuoco's Massapequa home. Fisher was having an affair with Buttafuoco's auto mechanic husband at the time.

The Buttafuocos have since moved to California and are no longer married.

The $15.95 paperback, being published by Barnes & Noble-owned iUniverse, starts with Fisher's troubled childhood, details her relationship with Buttafuoco, her prison time and her life and rehabilitation in the past five years.

In an excerpt, Fisher writes, "There were so many warning signs in my past. I am hoping that by reflecting on and writing about my life, some of it very painful, I can help stop others from getting into the same kind of trouble."

She also provides a warning to children and parents, saying, "I did these stupid things, and I'm here to tell you, this is what you should watch out for."

A spokeswoman said Fisher will earn an undisclosed "cut" from the book, but proceeds are also going to several organizations such as Million Mom March (search), Amnesty International American prison projects, the Legal Aid Society's Prisoners Rights Project and various local domestic abuse shelters.
