When I’m book hunting and I find an intriguing title, I’ll definitely look at the cover.
Irresistible? All right, so then I’ll read the blurb.
The few words written on the back of the book will either convince me to buy/borrow it, or will compel me to return it to the shelf.
That’s how important a blurb is.
It has the onerous responsibility – now that the title and the cover have played their roles – to get the reader to clutch the book to her chest, totter off to the nearest couch, and start reading.
