Children's literature is literature written for and/or marketed towards a primarily juvenile audience. While some books are authored for a youthful audience, others become associated with children through marketing or tradition. Still others are "crossover" books, read by children and adults alike. Literature addressed directly to children arose in Western Europe in the late 17th and early 18th centuries, becoming a very profitable industry in the 19th century. It includes picture books, fairy tales, animal stories, school stories, science fiction, fantasy, series fiction, chapter books, children's poetry, and other genres. Throughout its 300-year history, children's stories have reflected the values of the societies that produced them.
For love is a flower that grows in any soil, works its sweet miracles undaunted by autumn frost or winter snow, blooming fair and fragrant all the year, and blessing those who give and those who receive.
