This book is amazing! I am a huge fan of Percy Jackson and the Olympian series and The Heroes of Olympus series. I absolutely love Rick Riordan's books and are looking forward to read more of his books. I had recommended these books to my siblings and friends and they loved it too.
In this fourth book of Percy Jackson series, I was thrilled to see more relationship building between Annabeth and Percy!! Well, her actions was due to the situation that they were in..... I wont spoil the good part :)
The story has less humor compared to the other three but it is the best book out of the series that contains so much actions, gods and new characters. I highly recommend this book to the people who have been reading Percy Jackson series because they like the connection to the greek gods.
Like the other three, the book did end with a cliffhanger, and I think this book has the most unbelievably annoying one. It almost made me smack the book to the floor. :P
The thing that I really liked from this book is to see Luke(character from the first book) appear again in the story. Though he's still evil minded, I love having characters having back on scenes. Percy, since he is too kind hearted, allows Luke to join him and Annabeth to the quest, but eventually Luke goes behind their back.(you will notice it as you read the book)
I can't believe Riordan can get the readers to love the series more as you read the series. <3
