The 4th book in the Harry Potter series is yet another success! Prior to reading this book, I was quite nervous that it would follow the same storyline as the first three, rendering it a been-there, done-that. Rowling put my fears to ease within the fist chapter! This volume is much edgier than the first three. It addresses ideas and themes that reflect Harrys increasing age and maturity. Rowling wastes no time describing the premise of the storyline, trusting that her loyal readers are well-informed up to this point. She launches immediately into a brand new school year at Hogwarts, complete with new characters, new challenges, new love interests, and thus creating, new excitement. I highly recommend this to all Harry devotees!
