I completely loved the ending! It was very satisfying, even though its a little sad that the series has come to an end.
So anyway, Kronos advances on New York City to get to Olympus and destroy it. But of course, Percy, Annabeth, Grover, and the rest of Camp Half-blood (plus others :P) help to defend Olympus.
There is so much action and adventure in this book, its awesome! Plus its full of unending humor. Oh, and guess what? Pandora's Box isn't a box... its a jar! lol
Overall, I thought this series was a very good read. I love Greek mythology, but the books were also a very easy read. I personally haven't really studied Greek mythology, but you actually learn a lot from these books.
Have you read this book? If so, what did you think about it? If not, what do you think? Does it sound like something you might want to read? Leave me a comment! :)
