This book is a compelling story about climbing boys, or young chimney sweeps, in London in 1834. It follows the adventures of Tommy Simpson, as he struggles to find and be re-united with his father, faces the daily challenges of life as a climbing boy, and interacts with friends and street folk. Though his story is often darkened by his work and the period, it is brightened and redeemed by his growth in his journey and the humanity he shares with his "band of brothers."
