Felicity Trotman was born in Belfast, moving to Wiltshire as a child. Having studied graphic design and taken a History degree, she worked in publishing. She was a fiction editor at Puffin and at Macmillan Children's Books. Eventually turning freelance, she added history and military history to her children's specialty - though she admits that she prefers firing guns to writing about them. She is a churchwarden, school governor, and has spent many happy years as a member of the English Civil War Society.
