The Argo II is here and the Eight are assembled. Now, it's Isabelle and her friends' job to enter the ancient lands of Rome, defeat the Giants, save Nico de Angelo, and prevent Gaea's awakening.
However, things are never easy for a demigod.
Isabelle struggles to deal with the loss of yet another home. She tries to balance her two natures; one demigod, one Siren, but how much can she take on before her secret is ultimately revealed?

All rights go to Rick Riordan for the Heroes of Olympus: The Mark of Athena.
Isabelle Seymour and the plot surrounding her Siren heritage is my own idea, though.
