My reason for picking up a is the cover and title (I know never judge a book by it’s a cover) I usually do though. I never do this when I’m buying from an author that I’ve already read and no it’s going to be a good read. This only happens when I’m at a market or a book shop. I will look at the books cover/title then I would read the synopses and that usually makes my decision on whether I’m buying the particular book or not.
So what makes you buy a book eapecially if you haven’t bought a book written by the author before.
