About Cliffhanger

Cliffhanger is a children's novel written by Jacqueline Wilson and illustrated by Nick Sharratt, originally published in 1995. Wilson wrote the book after being asked by a producer to write an adventure two-part television series with a boy protagonist, which she was unfamiliar with. After writing the series, Wilson adapted it into a novel. The novel revolves around Tim being forced to go to an adventure holiday despite not wanting to. Cliffhanger was well-received by critics and readers. Wilson later wrote a sequel to the book called Buried Alive!.
