Spider-Man: House of M is a five-issue comic book limited series that ran concurrently with Marvel Comics' House of M crossover event in 2005. In the House of M pocket universe, mutants rule the world and humans are an oppressed minority. Magneto and his family, the House of M, rule the world from the island of Genosha. Much like the Fantastic Four:House of M miniseries, Spider-Man: House of M is a standalone story that takes place in the House of M universe, but the events do not affect the story of the actual House of M series. However, it is shown in the House of M series that the Peter Parker of the mainstream Marvel Universe remembers the life he had in this pocket universe. Source: Wikipedia (en)
