Perfect ending! I love Riordan's books and even though the final books in his series usually make me cry, they always end with hope. I also loved the humor in this series and the clean and not overly romantic moments. The action is perfect and I loved hearing from 9 different characters. I don't know how Riordan managed to keep them all in character, but it was well done. I really can't decide which character is my favorite, but I am hoping that some of them will return for The Trials of Apollo. I think Annabeth is probably still my favorite, but Leo was also fun. I feel like we saw Percy's flaws more with this series, which I liked and I feel like he became more of a traditional hero with flaws that could have caused a really bad ending. I think the pairings of characters works well and that we will see some of these couples again soon. I recommend this series to tweens all the way to adults and I love how Riordan tackles issues in his series and does so seamlessly with his plot. This is obviously a 5 cups of cocoa read for me and will definitely take the top spot for favorite middle grades read this year and possibly will take the top spot for my favorite read of the year. Keep the books coming Rick!
