Arthur Ransome's Swallows and Amazons series has stood the test of time. Ransome is not only a great storyteller, writing from first-hand experience, but each story celebrates eternally valuable qualities of practical knowledge, independence, and initiative. The twelve books are for children or grownups—anyone captivated by a world of sailing, adventure, and imagination.
Swallowdale (originally published in 1931) is the second title in the series. It follows the Walker family and friends through a shipwreck, a camp on the mainland, a secret valley and cave, and a thrilling mountain hike.
