Aurora Rising (The Aurora Cycle, #1)

by Amie Kaufman

Blue for the leadership corps. White for Cat and her fellow Aces. Green for the Brains in the Science Division. Purple for the Gearheads. Red for the Tanks. And lucky me, a bright, sunny yellow for the diplomatic corps to match my bright, sunny disposition.

Oblivious in their righteousness. Firmly convinced that any problem can be solved with enough faith or good hard work or, when all else fails, bullets.
