This book was so good! I just wish that I could have read it in one sitting. Grad school, you are ruining my life and taking all of my time! It was awesome to see all 7 of the heroes finally come together in one spot! I also hadn't realized how much I had missed Annabeth until I started reading the parts from her point of view! This book is way awesome! And to prevent spoilers I will quit by saying, that was not a cool cliff hanger, Mr. Riordan. I have to wait another year to see how it will be resolved!
