Ruta Rimas, editor at HarperCollins Balzer + Bray imprint presented a hands-on workshop on developing a character from scratch.
Look at your characters & ask questions like:
Who is your character? How does your character react to certain situations?
Write a scene where they do the exact opposite.
Ruta’s examples of well-developed characters:
Dexter (conflicted & complicated)
Max from Where the Wild Things Are
Frankie Landau-Banks from The Disreputable History of Frankie Landau-Banks
Katniss from The Hunger Games
Ruta recommends Writing The Breakout Novel by Donald Maass
