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

by Rick Riordan

“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.”

My favorite book of this saga by far!! It feels so cool to read it again now as an adult, being able to understand and process what I'm reading in a different way!!
