Michael Blake, Dances with Wolves, 1988

Dances with Wolves is a 1988 American Civil War novel by Michael Blake. Originally written as an unsold spec script, it was converted into a novel at the behest of Kevin Costner; it was finally adapted into a film of the same name, directed by Costner, in 1990. Union Lieutenant John Dunbar finds himself stranded in the wilderness and comes to live with a tribe of Comanche people, soon taking the name Dances with Wolves. The novel and film later came under criticism for similarity to Elliot Silverstein's A Man Called Horse. [Source]
