If you really, really loved the movie does reading the book ruin it? As much as I loved the Dreamworks version of How To Train Your Dragon, I’m so excited to get to know the Hiccup and Toothless that Cressida Cowell wrote in her middle grade series. Be warned! These books are almost nothing like the movie, but that’s okay. Many of my favorite books were introduced to me through a movie, but usually it’s the book that ends up making a difference in my life.
