“Mad Men” creator Matthew Weiner’s debut novel, “Heather, the Totality,” was one of the most-anticipated fiction books of the fall.

But following accusations from “Mad Men” writer Kater Gordon that Weiner harassed her when they worked together on AMC’s AMCX, -1.18% multiple Emmy-winning drama, the book, which was published on November 7, is in freefall with Weiner cancelling several events and the novel being met with a mixed critical and commercial reception.

MarketWatch has learned that a book event between Weiner and Susan Orlean, a writer for the New Yorker, scheduled to be held tomorrow night at the Ann and Jerry Moss Theatre in Santa Monica has been cancelled in the wake of the allegations.

The event’s website states: “This event has been cancelled. All attendees will receive refunds.”

The Santa Monica reversal follows the cancellation of promotional events for the book in Seattle scheduled for November 13 and an event Tuesday night in Portland.

Gordon alleged in an article for The Information that Weiner told her during a late night at the office that she owed it to him to let him see her naked while they were writing an episode of “Mad Men,” a show that drew acclaim for its portrayal of sexism in the 1960s. Weiner’s spokesperson responded: “He does not remember saying this comment nor does it reflect a comment he would say to any colleague.”

“Heather the Totality” was Weiner’s literary debut, and comes after he made a poorly received movie “Are You Here,” which was released in 2013. An Amazon project, “The Romanoffs,” is still scheduled to be released next year, starring Diane Lane, John Slattery and Aaron Eckhart.

The book has received positive blurbs from fellow authors Michael Chabon, James Ellroy and Claire Messud, but mixed reviews from critics. Entertainment Weekly thought “Heather, the Totality” was a “pretty thin debut” and The London Times declared it “disappointing” and asked if the book “was some sort of joke?”

“Heather the Totality” has an average rating of 2.9 stars on Amazon and is currently 1,616 on the Amazon bestseller list.
