Astrid Lindgren was born in 1907, and grew up at a farm called Näs in the south of Sweden. She began her writing career in 1944 after she won a children's book competition, with Pippi Longstocking published a year later. She published more than one hundred books in her lifetime and is still the most popular children's author in Sweden. Her books have been translated into more than sixty languages, and she received numerous honours and awards. Astrid Lindgren died in 2002. Mini Grey was given her name after being born in a Mini in a car park in Newport, Wales. She studied for an MA in Sequential Illustration at Brighton under the tutelage of John Vernon Lord. Mini also worked as a primary school teacher in Oxford, where she now lives.

She is the winner of the CILIP Kate Greenaway Medal and the Nestlé© Children's Book Prize Gold Award.
