The book is really good, so is the movie! After Meg's scientist dad goes missing, it's up to Meg, her little brother Charles Wallace and her new friend Calvin to save him from IT. They get help from Mrs.Whatsit, Mrs. Who, and Mrs. Which to save him. They go through many dangers to try to save him. I really REALLY think you should read the book first, so you won't be confused about the movie. It was really good, but the movie didn't include Aunt Beast, so heads up if you were looking forward to that part (I know I was). This movie is really good and I hope you watch it!
