The Heroes of Olympus

The Heroes of Olympus series is my favorite series Rick Riordan wrote. This series is full of action and is suspenseful. If you love to read action books I recommend this series. You will love them. This book is about a prophecy, that predicted seven demigods would unite to protect the earth from Gaea, the goddess of the Earth, before she wakes up. Gaea, on the other hand, is planning to destroy it.
