So I saw this book on the home page and I felt like I needed to make this review for once and for all. I read this book two years ago and I still remember what I think of it (thankfully). Anyway, this book made me realize that Heroes of Olympus is not for me. Why? Because in my opinion, Percy's story should've ended right after the Last Olympian. I feel like it was a nice ending and there was no need of keep making up adventures. Sure, I will see if I will read Trials of Apollo (unless he decides to make a series of it that is 7 books long and that is a big no for me). Rick Riordan is an amazing author. I admire him and his ability of making a book once a year practically. But dragging on a story because Percy is the favorite is too much for me. I loved the Kane Chronicles for example, and I'm really glad it ended after three books. But going back to this series, I feel like it was unnecesary and the trama of this series is not as good as the first five. But still, this is my opinion and I'm sure that a lot of people loved Percy's comeback. And now everyone's question: will I read Mark of Athena? Probably not. Peace out!
