Hampshire, 1940. Ellie Simpson is attached to an Air Transport Auxiliary base in Hampshire. Life as an ATA pilot is tough, but despite the long hours and danger, Ellie can think of nowhere she'd rather be. Not only does she love flying, but doing important war work, alongside new-found friends, provides a welcome distraction from worrying about loved ones fighting on the front line. Being an ATA girl is definitely exciting but, as Ellie soon finds out, wearing the distinctive blue uniform also means putting her life on the line every time she takes to the skies. It will take friendship and a strength she didn't know she possessed to help her country - and those she loves - to survive.
