New X-Men, Vol. 4: Riot at Xavier's

Grant Morrison, Frank Quitely

In a world where humans have made mutants the victims of horrible discrimination, Professor Xavier's School For The Gifted is a sanctuary, a safe haven for oppressed mutant youth. But the unimaginable happens when a student reinvents himself as Kid Omega and decides to take over the school. It's mutant vs. mutant...will the school ever be the same?
