“What words/phrases in a blurb make a book irresistible? What words/phrases will make you put the book back down immediately?
Other than a favorite author's name, I don't know that there are any particular words or phrases that make me buy or not buy a book. If the plot or themes pique my interest, I might buy the book. If they don't, I won't.
I'm much more likely to buy a book because someone I trust recommended it than because of what the blurb says.
