The Battle of the Labryinth by Rick Riordan

Percy Jackson and the Olympians: Book Four - I got a little bogged down in the beginning but the last 25% of the book was great and I can't wait to read the last one. Agian there is a quest, and this time to save camp. The mosters and situations have built through out the books and get greater as we go along. Riordan is very good at leading you along and many times I am not sure what is going to happen. I like that. Looking forward to see what happens in the last book. What will the prophecy hold??
