You can judge a book by its cover. Grab a book off the shelf read it and if you dont like it then return it to the library and repeat. I dont finish half the books I get out and I dont waste time on them. If I dont enjoy it after the first few chapters I drop that shit. Its expanded my taste I found a lot of authors that are really good. Books I thought were going to be shit turned out good and ones i thought good turned out shit(time travelers wife)
