HarperCollins Publishers LLC says in court papers filed Thursday in New York that the book was due in 2005. Gotti notified HarperCollins last September she was terminating the contract.
The lawsuit says the daughter of the late "Dapper Don" John Gotti and star of the reality show "Growing Up Gotti" did not return the $70,000 advance.
Literary agent Frank Weiman says his client will return the money when he gets her another deal.
Weiman says Gotti made her book deal with former publishing heavyweight Judith Regan and that Gotti canceled because Regan and other editors his client dealt with left HarperCollins.
