The Battle of the Labyrinth (Percy Jackson and the Olympians, Book 4) - Rick Riordan *Just finished re-reading it! I love these books. :] So much. And the last two especially are wicked intense. Hehe.*original review: AMAZING!!! I LOVED IT!!! I'm always glad to see a series that can keep itself going without the author running out of ideas. Like the three books that come before it, The Battle of the Labyrinth is exciting, funny, and overall very enjoyable. I also love its strong characters. Fans of the series will NOT be disappointed :D
