Gillian Shields was born and brought up in Yorkshire, in the north of England. As she grew up, she had two passions:books and theater. Gillian's love of books led her to read English at St. Catharine's College, Cambridge. After university she studied acting in London. She then taught in a drama school, the Academy of Live and Recorded Arts, for several years, becoming Vice Principal. She recently taught English and Drama at Beechwood Sacred Heart, a girls' boarding school.
Having children gave Gillian an excuse to carry on reading children's books, as well as a motivation to write them. She has a son and a daughter, and is married to Brian, who works for the New York Times Media Group.
