I have loved to read since I was little. I would borrow many books from the library and still borrow to this day, but I also purchase books (mostly for my kids) and freebies on Kindle. I read as much as I can daily. Sometimes I read several books at one time. I don't have a preference of paper book over an ebook, I just love to read. Keeping lists of what I have read is a good way for me to remember.
Definitely, a case of Book is better than the movie. There was a lot that happened in Book 1 that should have been its own movie and there was a lot in Book 2 that was enjoyable and really added to what you know about Shannon and her friends and the mean girls who never seem to grow up. It brings in Althea, so if you watched the movie before you read this book, it takes care of all the questions and is a really good book. It would be okay to read first since it gives background information on the previous book without being too much or too little. I did enjoy this book and finished reading it while my husband drove us home from Indiana.
