Do you read the inside flaps that describe a book before or while reading it?
It depends on why I’ve picked up the book. If it’s something that caught my eye but I’ve not heard of, I’ll read at least the first few sentences of the flap. If it’s been recommended by a friend or blogger, I typically get enough information from them and prefer not to gain any additional details from the blurb. I don’t rely on the flaps to decide whether I’m going to enjoy a new writer, as they’re not written by the author him- or herself; I’ll read the first page, or flip to somewhere in the middle and read a few sentences to get a feel for their voice.
How about you, how much do you like to know about a book going in? Do you go on intuition or get the details from the blurb, reviews, other sources?
