Edith Nesbit was a mischievous child who grew up into an unconventional adult. With her husband, Hubert Bland, she was one of the founder members of the socialist Fabian Society; their household became a centre of the socialist and literary circles of the times. E. Nesbit turned late to children's writing. Her first children's book, The Treasure Seekers, was published in 1899 to great acclaim. Other books featuring the Bastable children followed, and a series of magical fantasy books, including Five Children and It also became very popular. The Railway Children was first published monthly in the London Magazine in 1905, and published as a book in 1906, which has been in print ever since.
