I have some questions.

1. Do you think that Ella's prophecy about the Mark of Athena burning through Rome has something to do with the Prophecy of the seven?

2. Why do you think Annabeth is one of the seven?

3. Should Jason be with Reyna or Piper?

4. Will Rick introduce some new characters in the next book?

5. What's up with Poseidon? We haven't heard from him.

6. How many demigods are in Camp Half Blood during the Son of Neptune?
