Don't ever read the actual version... you will hate yourself and the book.
Janet Evanovich??? If so the movie One For the Money is based on one of them.
The Great Gatsby is my all time favorite book. I was Daisy for Halloween. I own two fancy, expensive limited edition books, that one and To Kill a Mockingbird. Fell in love and never looked back.
If people looked at my bookshelf, they would be confused because my taste in novels is all over. If people like funny books, I recommend any of Tucker Max's books, fair warned it is for an older audience. If people like sports books, my personal favorite is Moneyball and if you want to cheat, yes it is a movie. Another classic favorite of mine is Wuthering Heights. If you like history, take a stab at The Mayflower Papers, boring at times but an overall good read.
And for all of you who read the 50 Shades... so did my 75 year old grandma. She read them all in 2 days and talks about them ALL the time. Awesome.
