This deluxe Library of America volume presents one of the landmark books of the twentieth century together with rare letters, speeches, and other writings that reveal the personal courage and passionate commitment of its author, environmentalist Rachel Carson.

Now for the first time, in previously unpublished and newly collected letters, Carson''s groundbreaking expose of the unintended consequences of pesticide use comes together piece-by-piece.
