It is a story of one man, Howard Roark, and his struggles as an architect in the face of a successful rival, Peter Keating, and a newspaper columnist, Ellsworth Toohey. But the book addresses a number of universal themes: the strength of the individual, the tug between good and evil, the threat of fascism. The confrontation of those themes, along with the amazing stroke of Rand's writing, combine to give this book its enduring influence.
