So right now I'm writing a book about Foxface's perspective and I had a couple ideas.

I might write books from different characters perspectives.

74th Hunger Games Tributes:
Marvel
Glimmer
Clove
Cato
District 3 Boy
Thresh
Peeta
(I'm not doing Rue because there is already a book like that in the library. Look it up!)

75th Hunger Games Tributes:
Cashmere
Gloss
Enobaria
Brutus
Beetee
Wiress
Mags
Finnick
Johanna
Peeta (again)

Others:
Gale
Prim
Effie
Haymitch
Mrs Everdeen
