His second book, The Dark Wild, won the Guardian Children's Fiction Prize. The third book in the trilogy, The Wild Beyond, was published in 2015 to critical acclaim. His next book for children, There May Be A Castle, will be published in October 2016.

The son of the late Paul Torday (author of Salmon Fishing in the Yemen) Piers recently completed his father's final unfinished novel, The Death of an Owl (Weidenfeld & Nicolson, April 2016).

In regular demand as a speaker at schools and festivals, Piers is also a reading helper with Beanstalk, a former judge on the Guardian Children's Fiction Prize, a Patron of Reading at Heathmere School and a trustee of the Pleasance Theatre. Born in Northumberland, he now lives in London with his husband and hopefully a cat.
