Goodreads Summary:

All year the half-bloods have been preparing for battle against the Titans, knowing the odds of victory are grim. Kronos's army is stronger than ever, and with every god and half-blood he recruits, the evil Titan's power only grows.

While the Olympians struggle to contain the rampaging monster Typhon, Kronos begins his advance on New York City, where Mount Olympus stands virtually unguarded. Now it's up to Percy Jackson and an army of young demigods to stop the Lord of Time.

In this momentous final book in the New York Times best-selling series, the long-awaited prophecy surrounding Percy's sixteenth birthday unfolds. And as the battle for Western civilization rages on the streets of Manhattan, Percy faces a terrifying suspicion that he may be fighting against his own fate.

What happened in The Last Olympian?

  • Percy and Rachel drive to look at the ocean. Rachel tells Percy that her father wants her to go to Clarion Ladies Academy, a finishing school for rich kids. She isn’t keen on this idea.
  • Blackjack lands on the car. He has brought Charles Beckendorf with him. Beckendorf tells them that it’s time for them to take out Princess Andromeda, a ship that Luke is on.
  • Rachel kisses Percy for good luck. Or for feels, I guess.
  • Percy and Rachel sneak onto the ship and are able to put some explosives in the engine room before Percy is captured.
  • Percy is taken to Luke, who is still possessed by Kronos. They fight, and Kronos lets slip that there’s a spy in the camp.
  • Beckendorf shows up and stalls while he waits for the explosives to detonate. Percy doesn’t want to leave Beckendorf but he is left with no choice. The ship blows up as Percy jumps off the ship.
  • Percy is knocked unconscious and he dreams of being at Mount Olympus. He overhears Krios and Hyperion plot to destroy Olympus. Percy spots Nico listening in too.
  • Percy wakes up in Poseidon’s kingdom. Tyson is there with him, and he takes him to see Amphitrite and Triton. Poseidon tells Percy that he’s battling Oceanus.
  • Poseidon confirms that Beckendorf is dead. He tells Percy to return to Camp Half Blood.
  • Percy returns and tells everyone what happened on the Princess Andromeda. The war council tells Percy and Annabeth to retrieve the prophecy from the Oracle. They do so, and when they get back the council is in chaos and arguing.
  • Percy reads the prophecy and realises he’ll die.
  • Percy tells the others about the spy in camp. Everyone starts accusing each other.
  • Chiron reveals that Typhon is free and making his way to Olympus.

  • Grover has completely disappeared at this point and his link to Percy is weakening.
  • Percy bumps into Nico, Leneus, and Juniper talking about Grover in the woods. Percy tells Leneus he must help Grover.
