The Last Olympian

The Last Olympian is the final installment in Rick Riordan's Percy Jackson series. Throughout the 400 pages, Percy and his friends must fight the Titans while the gods try to rescue the world by fighting Typhon ( a giant with 100 heads and each eye shoots lava) who got out of the volcano he was trapped in. Percy and friends fight the Titans led by Kronos by making Percy almost immortal in the same process that Achilles almost became immortal, dipping him in the river, Styx. In the end, it comes down to Percy and Annabeth in the throne room against Ethan Nakamura, the son of the goddess of revenge, Nemesis, and Luke who has been taken over by the almighty Kronos. Percy finds out by Ethan's dying breath that Luke had been dipped in the river, Styx, as well. Then in an instant, Luke gains enough control of his body to complete one action-kill himself. Percy has a tough decision, either to kill Luke himself or give Luke the dagger to commit suicide. Percy chooses the latter because he believe that that was what Luke wanted. In addition to killing himself, Luke also kills Kronos who possessed his body. Finally, the gods defeat Typhon and everyone is safe. But Percy has one last demand for saving the world. The gods must all take claim to their children.
