Summary

This book is outstanding... To keep the goddess Gaea from waking, the 7 half-bloods known as Percy, Annabeth, Frank, Hazel, Piper, Jason, and Leo need to fight what seems like all the monsters you could ever imagine. But, in the meantime Nico, Reyna, and Coach Hedge are bringing the Athena Parthenos back to camp to prevent Gaea from rising there and maybe prevent war between the Greek and Roman half-bloods.
