Heroes of Olympus: The Lost Hero by Rick Riordan – review

A fast, heart-pounding story of three demigods, two Greek and one Roman. The characters go on an adventure to stop the awakening of Gaia, who is goddess of the Earth, and Polyphemus, who is the king of giants. I loved the part where Piper falls off the Grand Canyon bridge and Jason flies to catch her. I am really looking forward to finding out what will happen in Rick Riordan's next book, Son of Neptune.
