Katherine Langrish is a British author[1] of fantasy for children and young adults.

She was encouraged by her parents, and by the fact that her grandmother was a Yorkshire novelist and playwright of the 1930s, Leonora Thornber.

She worked for six years in the Information Office at Lloyd's Register, London, before moving to France and then to the United States, where she became involved in oral storytelling to schoolchildren.

On returning to England in 1999, Langrish began writing Troll Fell, which was published to critical acclaim by HarperCollins in 2004.

Her books have been published in Japan, Russia, the Czech Republic, Iceland, Spain, Italy, Brazil, the US, Australia and Canada.
