My favorite book (series) is Harry Potter, and this book gave it a run for its money in the magical department. What made this book stand out so much to me was the romance. I don't read romance very often, so I don't have much to compare it to, but I thouroughly enjoyed the makeout scenes and lover's quarreling next to the wizarding. Magical worlds are so different from our science, non-magical culture, so imagery is especially important in such magical writings, and Rowell definitely does not disappoint. If you like romance and/or magic, then I recommend you read this.

I also realized after reading this book that it is actually a spin off addition to her other book (series?) FanGirl. I was not aware of this when reading Carry On, so this book is definitely a good read whether or not you've read FanGirl (but the experience might be heightened if you did).
