I feel sorry for the ghostwriter

Just saw this in Publishers Marketplace:

The younger sisters on E!'s hit reality show Keeping Up with The Kardashians Kendall Jenner and Kylie Jenner's dystopian novel that takes place in a world none of us have ever seen and will follow two sisters on a journey filled with terror, mystery, drama and love, to Charles Suitt of Karen Hunter, for publication in Summer 2013, by Mel Berger of William Morris Endeavor (NA).
"A world none of us have ever seen."

Yeah. I've seen too much of the Kardashian world, thankuverymuch.
"A world none of us have ever seen" might mean "we haven't hired the ghostwriter who will develop said world yet."

I know people who channel one celeb, but two? No thank you.

PS Also, subject-verb agreement would argue for "none of us HAS ever seen"
Hahaha I thought the same thing! Considering we are in the business of writing... you'd think....

But no. This is not the business of writing... it's the business of making money.... and sadly they don't need grammar, or a plot, to make loads of it!
