In 1965, a strange family of outcasts made their debut in the pages of Fantastic Four. The uncanny Inhumans emerged from their mysterious Himalayan refuge, Attilan, and quickly all but took over the FF's magazine. The origins of the Inhumans--Black Bolt, Medusa, Gorgon, Triton, Karnak, Crystal and Lockjaw--were revealed month after month in FF until reader demand gave them their own feature in the back pages of Thor. Now the story of the Inhumans and their wondrous, secret refuge is collected together--from the very beginning--for the first time ever! From Medusa's debut as a member of the Frightful Four to the battle to break the Great Barrier, it's all here in incomparable Lee and Kirby fashion!
