The protagonist is Tom, a young chimney sweep, who falls into a river after encountering an upper-class girl named Ellie and being chased out of her house. There he appears to drown and is transformed into a "water-baby",[3] as he is told by a caddisfly—an insect that sheds its skin—and begins his moral education. The story is thematically concerned with Christian redemption, though Kingsley also uses the book to argue that England treats its poor badly, and to question child labour, among other themes.

Charles Kingsley (12 June 1819 – 23 January 1875) was a broad church priest of the Church of England, a university professor, social reformer, historian and novelist. He is particularly associated with Christian socialism, the working men's college, and forming labour cooperatives that failed but led to the working reforms of the progressive era. He was a friend and correspondent with Charles Darwin. He was also the uncle of female explorer Mary Kingsley.(Excerpt from Wikipedia)
