In my opinion, I really liked this book. The story where Jace, Leo, and Piper go on a quest in the modern world to save Camp Half-Blood where all of the children of the gods go to. They need to protect it from the Greek mythology monsters who attack the gods and the camp. Another reason why is it taught me a lot of information about Greek Mythology including the gods and monsters they used to believe in. The last reason why is there are a lot of mysteries that will make you want to keep reading until you figure out what happens. My favorite part is when they battle the Greek monsters and minions who try to stop them from saving Camp Half-Blood while having to save each other from them and work together as a team to save the world from the monsters. You might like this book if you like action, Greek Mythology, Fantasy, comedy, and mystery. You should read this book because it can help you learn a lot about Greek Mythology. The story is very interesting and unique because it is a story about Greek Mythology that takes place in the modern world with all of our current technology, unlike other Greek Mythology books which just tell facts about Greek Mythology or stories in the old world about Greek Mythology.
