The Day Boy and Night Girl – also referred to as The Romance of Photogen and Nycteris – first appeared in Harper’s Young People as a series between December of 1879 and January of 1880. Regarded as George Mac Donald’s best work, it features a witch who, in her pursuit of total knowledge, performs an experiment to mould two people from birth by strictly controlling their environments. Many of the finest stories of magic and fantasy, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
