The third book of the Harry Potter series digs even deeper into the wizarding world. Adding yet another important character to the series adds more interest and depth to the main character. The fast paced book pulls the reader in and holds them tight through the entire story. Reading these stories as an adult is even more gratifying than it was when I read them as a child. You catch more details and jokes and it makes it a more satisfying read.
The fourth installment of the Harry Potter series is a little less deep than the first three. It is chalk-full of action, but the character development is lacking compared to the other books. I enjoyed reading about Harry getting through the challenges and once again defeating Voldemort, and I enjoyed the quirky romantic aspect of it.
