From the bestselling author Katie Flynn. Growing up in the Yorkshire Dales, Maddy Hebditch can't imagine the changes that war will bring when she joins the ATS.

1938: Maddy Hebditch has been living in poverty with her cantankerous grandmother since she was orphaned when she was just five, and it's a constant struggle to stay out of the workhouse.

Until war breaks out and everything changes.

All four face dangers as the war worsens, but when Tom is terribly injured, Maddy's world falls apart...
