In The Edge of the Sea Rachel Carson introduces us to the 'strange and beautiful place' where the sea meets the land. She explores a tide pool, an inaccessible cave, and watches a lone crab on the shore at midnight. From these, and other, encounters she offers us not just a scientifically accurate study of the ecology of the seashore, but also a hauntingly beautiful account of the fragile balance of life found at the edge of the sea.
