Washington (CNN)It's only been two days since its debut, but already reviews for Ivanka Trump's latest book, "Women Who Work: Redefining the Rules for Success," are in.

They're not great. In fact, some are downright brutal. A sampling:

"Witlessly derivative," said The New York Times' Jennifer Senior.

"A grab-bag of generic work-life advice," wrote Emily Peck of HuffPost.

"It is really vapid," is the opinion of Slate's Michelle Goldberg.

"Trump's lack of awareness, plus a habit of skimming from her sources, often results in spectacularly misapplied quotations," said NPR's Annalisa Quinn.

It gets an average 1.2 stars on BarnesandNoble.com.

Over on Amazon.com, there's no middle ground. People either love it or hate it. Thirty-nine percent give the book, which is a guide for working women, five out of five stars. Two percent give it four stars, one percent give it three stars, and 0% give it two stars -- however a whopping 58% give it one star, the lowest rating.
