Lucy Maude Montgomery (1874-1942) was a Canadian author best known for a series of novels beginning with Anne of Green Gables, published in 1908. She was a master of children’s literature. The Blue Castle is considered one of L.M. Montgomery's few adult works of fiction and it has grown in popularity since being republished in 1990. It has been adapted for the stage several times. The bewitching plot and the images and symbolism applied in the novel are the highlights which together make the novel a success. 
Valancy Stirling, The heroine of the novel, is twenty-nine, unmarried, and has lived her entire life with her gossip-minded families who actively discourage happiness and treat Valancy like a child. When Valancy receives a letter which tells her that she has about only one year to live, she suddenly realizes that she has never been happy in her life, and she makes her mind to be master of her own life and rebels against the colorless life her family have imposed on her.
