Anybody read Ender's Game? Q is the real life version of Peter Wiggan's Locke and Valentine's "Demosthenes:
After the rebellion of the small human colony on Lusitania in Speaker for the Dead to protect the future of the intelligent alien species, Starways Congress sends a fleet to Lusitania to regain control, which will take several decades to reach its destination. Valentine Wiggin, under her pseudonym Demosthenes, publishes a series of articles revealing the presence of the "Little Doctor" planet-annihilating weapon on the Fleet. Demosthenes calls it the "Second Xenocide," as using the weapon will result in the obliteration of the only known intelligent alien life. She also claims it to be a brutal crackdown of any colony world striving for autonomy from Starways Congress….
Public anger spreads through humanity, and rebellions nearly ensue on several colonies."
