The Australian socialite and businesswoman Roxy Jacenko has had to pulp the first copies of her latest book after a quote on the cover mistakenly said she “never fails to disappoint”.

Jacenko, a PR specialist and former contestant on Australia’s Celebrity Apprentice, said the “nightmare” endorsement was an honest mistake and was meant to say she “never fails to deliver”.

The less-than-flattering quote made it past all proofreaders at publishing house Allen & Unwin, and was spotted only when advance copies of Roxy’s Little Black Book of Tips and Tricks had been sent out.

Written in only six weeks, Jacenko’s book bills itself as a “no-bullshit guide to PR, social media and building your brand”. Glowing reviews on the back cover describe the publicist as “street-smart and hard-headed” and a “totally tenacious PR expert”.

“Roxy never fails to disappoint, and this book is an easy, interesting read that people in a lot of professions (not just in PR) could learn something from,” the uncorrected quote said.

It was printed due to “a proofing error made by our editorial department”, Allen & Unwin said.

Jacenko told Sydney’s Daily Telegraph the mistake made it past six proofreaders at Allen & Unwin, and it was a friend of hers, who had received an early copy, who pointed it out.

“It’s a f**k-up, but Jackie’s a friend,” Jacenko said. “It certainly should have said ‘Roxy never fails to deliver’.”

Allen & Unwin would not disclose how many books had been printed with the error. The publisher said it would correct the quote and the book would still meet its late-November release date.

“There was a misprint in an endorsement quote from radio announcer Jackie O,” a spokesperson said. “This was missed in proofing, but subsequently corrected prior to the book’s publication.”

Jacenko has previously written three fiction books, and is married to the high-profile former stockbroker Oliver Curtis, who was convicted of insider trading in 2016.
