On a wing and a prayer / by Ruby Jackson.

The third in a series of books featuring four young women whose lives will be forever changed by WWII. Rose Petrie is desperate to do something for the war effort. Despite the daily hardships and the nightly bombing raids, her sister, Daisy, and their friends all seem to be thriving in their war work. Rose is doing her best down at the munitions factory, but she is dealt a blow when her childhood sweetheart, Stan, tells her he doesn't feel the same way about her. Determined to get away and make a new start, Rosie decides to put her mechanical skills, learned from her father and brothers, to good use and signs up for the Women's Auxiliary Service, or ATS. But Rose discovers that delivering fruit and veg in her father's greengrocer's van is very different to driving trucks for the army in a country under seige.
