BOOK ONE In a world of change and constant battle for superiority, one must always rely on instinct-impulse. Impulse is what will carry Sophia Grey through the Cold War and beyond, a period of time where tension is not only evident between humans, but also between humans and mutants. Will she accept her fate, or make anew a world for herself aside from the one that won't accept her? Set during the time of X-Men First Class. *disclaimer* all characters except for Sophia Grey are Marvel's property Book 2: Relapse is now up!
