The Last Olympian (Percy Jackson and the Olympians, #5)

by Rick Riordan

“I am here because when all else fails, when all the other mighty gods have gone off to war, I am all that’s left. Home. Hearth. I am the last Olympian. You must remember me when you face your final decision.”

“Seven half-bloods shall answer the call. To storm or fire, the world must fall. An oath to keep with a final breath, And foes bear arms to the Doors of Death.”
