After accusing Hollywood mogul Harvey Weinstein of rape for years, actress Rose McGowan has recounted the sexual assault she claims occurred after their first meeting more than 20 years ago.

In her new book BRAVE, the actress discusses the day she alleges the former movie mogul raped her in 1997 at the Sundance Film Festival. McGowan, 44, has previously accused Weinstein of rape on Twitter but did not elaborate on the allegation.

McGowan, who consistently refers to Weinstein as “the Monster,” claims the tycoon invited her to a meeting at a restaurant before heading upstairs to talk about her career.

McGowan says of her feelings prior to the encounter, “I was certain we would be working together for many years to come, and we were here to plot out the grand arc of my career.”

But he held her down in a Jacuzzi and performed oral sex on her while masturbating, she wrote.

“I felt so dirty. I had been so violated and I was sad to the core of my being. I kept thinking about how he’d been sitting behind me in the theater the night before it happened. Which made it – not my responsibility, exactly, but – like I had had a hand in tempting him,” she wrote. “Which made it even sicker and made me feel dirtier.”

McGowan said that she went to a photo opportunity for Phantom, another Miramax picture she was in, just after the rape and informed Ben Affleck what had occurred. “Goddamnit. I told him to stop doing that,” he allegedly said. This accusation has elicited no response from Affleck.

While the incident is not classified as rape by the law, McGowan thinks it was: “Rape to me is any violation of my body. If you enter my body via tongue, fingers, penis, object without my consent, that to me is rape and I need no law telling me what I know to be true.”

Weinstein’s lawyer, Ben Brafman, sent a statement to PEOPLE in response to McGowan’s claims.

“Mr. Weinstein denies Rose McGowan’s allegations of non-consensual sexual contact and it is erroneous and irresponsible to conflate claims of inappropriate behavior and consensual sexual contact later regretted, with an untrue claim of rape.” McGowan “chose to demand money” from Weinstein, according to his spokesman, and afterwards worked and appeared with him.

McGowan’s account is similar to that of many other actresses who have accused Weinstein of sexual misconduct. Weinstein has been accused of sexual harassment and assault by over 90 women, with the bulk of the tales alleging that he scheduled meetings with actresses in his hotel room and then made sexual advances or worse when they arrived.

“Any allegations of non-consensual sex are unequivocally denied by Mr Weinstein. Mr Weinstein has further confirmed that there were never any acts of retaliation against any women for refusing his advances,” a representative for Weinstein in the US told the Guardian.

“Mr Weinstein obviously can’t speak to anonymous allegations, but with respect to any women who have made allegations on the record, Mr Weinstein believes that all of these relationships were consensual.”

Brave will be available at bookshops on January 31.
