The final concluding book to the Percy Jackson series. This book was great. Compelling and brilliant, Percy and his friends, now years older than when the series began, must take down Kronos in order to save the world. Everything was really good. Although I am saddened by the fact that the series has come to an close, I am heartened that it had such a wonderful ending. We will be seeing more of Percy, however, in the Heroes of Olympus series, which I am eagerly anticipating the third book in the series this fall. The Heroes of Olympus is to a five-part series, just like Percy Jackson. Loved it!
