100 Days, 99 Nights (and 15 Saturdays without Dad's Pancakes) by Alan Madison, illustrated by Julia Denos
Esmerelda Swishback McCarther has spent most of her seven years living in four different countries on four different continents with her military family. Arriving back in the United States, she and her brother begin school in a suburb of Washington, DC. Unfortunately, her father must leave for a tour of duty-100 days and 99 nights. Saddened and fearful for him, Esme gives him the precious remnant square from her "blankie" to take with him. While he is away, she struggles to remain dutiful and strong, traits that her family values.
