For years Percy Jackson has been warned about the Titans, about the lengths they're willing to go to to end Olympus. Yet it's only after it happens, when Manhattan is burning around him, that he realises that is only the beginning. With the gods now gone and the Titans hunting down the survivors, it's up to the demigods to keep Olympus standing.

At the age of sixteen, everyone presents as Alpha, Beta or Omega. Percy was always expected to be a leader - as a child of Poseidon he was unlikely to be anything else - so it wasn't a surprise for him when he turned out as an alpha. He doesn't think much about what's expected of him, until he's almost buried alive with an omega. The gods can hardly blame him for what happens.

The war between the gods and Titans is over and Seth had recovered his memories to find out he is the eldest son of Kronos and is known as Theron. He betrayed the Titans and saved Olympus, then willingly descended into Tartarus to revive his family. Now alone in the Pit he must find the other Titans before the gods descend into another war, one that threatens the world. Book 2.

Annabeth managed to escape Tartarus and join the seven in the war against Gaea, but Percy was left behind. Now, three centuries later the Doors of Death are opening again and a quest will enter the Pit to free the son of Poseidon. Nine heroes will enter the Pit, finding unexpected allies and enemies they never thought were still alive as they search for the Hero of Olympus.
