The Night Flyers — Elizabeth McDavid-Jones

It's 1918. Pam Lowder and her papa raise the best homing pigeons on the North Carolina coast -- homers with the rare ability to fly at night. While Papa's away in World War I, a stranger with a foreign accent comes to town. Soon Pam's best birds start to disappear, and Pam is sure the stranger is stealing them. Instead, she finds evidence of something much worse. Could the stranger be an enemy spy, threatening everything Pam holds dear -- even Papa?
