Série rouge is a paperback series for 14–16 year olds learning French. Authentic French paperbacks for teenagers, which may be at the right cognitive level, are usually too difficult linguistically for students who have only been studying French at school for a limited amount of time per week. Série rouge provides a stepping stone, offering stories of romance, murder and mystery, everyday stories and true stories, all written in straightforward French, in an easy-to-read format. The illustrations have been carefully chosen to help readers follow the text more easily. Chère Lambert! follows an exchange of letters between Sandrine Lambert (just 15, with blue eyes, a Libran, owner of a dog called Taxi) and Laura Wilmot (absolutely NULLE EN FRANÇAIS). The letters are often funny, sometimes touching and serious.
