Rachel Carson is known best for writing Silent Spring. It’s a condemnation of DDT and other toxic pesticides and how they hurt the environment. When the book was published in 1962, it was full of new information that shocked most Americans. Silent Spring led to a radical shift in national pesticide policies, and the book has been credited with sparking the modern environmental movement. But before all that, Carson built a summer house. It was at the edge of a cliff on the coast of Maine, on a little island called Southport. And it was on that island that Carson met Dorothy Freeman. This is the story of Carson and Freeman’s relationship. It grew from their shared love for the natural world — and one species of bird in particular: the Veery, a kind of thrush. Plain looking as it is, the Veery has a beautiful song. And that song matters to Rachel and Dorothy. It's an expression of the wonder they experience in nature — and in each other.
