Things I Know About Love is a great book for girls who love romance books, or people who like the story to be happy. Written in a typical teenage / young adult style, the author gets right inside a girl's mind, who is just taking her first steps into love. This book also helps you understand what a teenager goes through when suffering from a life threatening illness like leukemia, but for the most part, it isn't too depressing.
However, right at the end she drops a huge bombshell on the reader - it almost made me cry! The book is amazing and happy all the way through but the end leaves you feeling rather depressed, but it does change your outlook on life, and helps you understand how to deal with teenagers going through serious illnesses.
I would have given this book 5 stars, but unfortunately the ending changed my mind.
