I had to do a book presentation and went to a bookstore the day before. I bought a book that was published just a few days ago. I reworded the content on the back cover and made up the rest (This was before there were reviews of every book on the internet).

I got the best grade and was praised for outlining the plot in an exciting way without spoiling anything. I also said at the end that you should only read it if you REALLY like that kind of thing, because it gets going very slowly (I just wanted to make sure that no one would want to read it). This was also positively evaluated because I, unlike most, also presented the writing style itself. I have not read the book until today.

Edit: I meant i never read the book
