There's been a lot of talk of Suzanne doing another book on the 1st Quarter Quell since there was quite a bit of lead up to it in SOTR, especially regarding Plutarch's story. Very likely Plutarch will be 16 years old and a mentor to one of the tributes.
Anyway - I always found the idea of the 1st Quarter Quell hysterical. Imagine your district voting for you to die, only to come back a winner when they thought you were never coming back.
