List the titles of the books you read for pleasure that you enjoyed most in the past year (150 words or less)
Required readings are what you were required to read in school such as The Great Gatsby and House on the Mango Street (at least I had to).
Books for pleasure are, quite frankly, what you read for pleasure. Any books that you specifically picked out to read because they’re fun, interesting etc. and not required by any means.
