Pearl has given up on her dreams of being a journalist after being denied a promotion because of her gender.

Pearl befriends Met WAAF Jenny as well as Australian pilot Greg , who she guides home safely during an emergency. Pearl's journalism background doesn't go to waste, however - a series of thefts from pilots rekindles her investigative fire and she is soon caught up in the mystery. But when all signs point to the perpetrator being her sister, she finds herself up against the clock to prove her sister's innocence... A captivating and heartwarming WWII saga for fans of Daisy Styles and Johanna Bell.
