Have you ever wanted to breathe under water? Or be able to control water at your own will? Well, Percy Jackson soon discovers he can when he figures out he is the son of Poseidon (in Greek mythology, the God of the sea). And being a demi-god is no cake walk. In the book, you will see all the trials he faces trying to return Zeus’s master bolt. If you are a fan of Greek mythology, or kids with powers, you will love this series. Also if you enjoyed any fantasy books such as the Harry Potter series, though they are very different, you would enjoy this book as well. I give these books 5/5.
