El Manantial

The novel follows Howard Roark, a young and innovative architect, as he battles against the conventional and traditional architectural establishment.

Roark's individualism and integrity are contrasted with characters like Peter Keating, who rises through his profession by conforming to societal expectations, and Ellsworth Toohey, an architectural critic who advocates for the subordination of individual creativity to societal norms.

The story also involves complex relationships and conflicts, particularly with Dominique Francon and Gail Wynand, highlighting themes of egoism, individualism, and the struggle against collectivism.

The climax of the book features Roark's trial and his lengthy speech defending his actions and advocating for individual rights and egoism.
