Systematically abused and degraded children do not suddenly turn into well-adjusted members of society when removed from the abusive situation. Nor do they tend to be very trusting of others, or forgiving. Sequel up.
As Magical England grinds itself through civil war and Magical Europe at large collapses in upon itself, Harry hunts through it all. Dumbledore has disappeared, Lucius Malfoy has publically fallen out with Fudge, and most the population of Hogwarts has fled to America, bringing many families of Muggleborns with them. Sequel to Brutal Harry. Rated for violence/messiness.
