Lone Pine is a series of children's books written by English author Malcolm Saville. Although they were written over a 35-year timespan, between 1943 and 1978, the characters only age by a few years in the course of the series. The earlier books evoke visions of an outdoor 1940s and '50s childhood reminiscent of Enid Blyton's Famous Five books, in which children are allowed to have adventures, explore strange places and encounter villains without adult supervision. These Lone Pine books were illustrated by Bertram Prance (1889-1958). The later books adjust to the mood of the 1960s and '70s, as the older characters grow into their late teens and new characters join the Lone Pine Club.
