It's 1940, and Jody is moving with her military family yet again--this time to a small naval base in Pearl Harbor. She's always created a "top ten" list for each new home to help her adjust, and with Hawaii being so beautiful and her loyal dog Happy by her side, it's easy to find things to add.

But Jody's mom is convinced the island is dangerous and starts constantly practicing first aid. Jody also learns that Happy is getting older and beginning to slow down. To cope, she makes a list of fun things they can do together. "Operation: Happy" gives her something to focus on beyond the scary new experiences, like air raid drills and Yellow Fever vaccinations.

Before long, everyone's worst fears come true: Pearl Harbor is attacked. In the aftermath, Jody's father must stay behind as the rest of the family is evacuated, and Jody promises him she will keep everyone together. But things are hard in San Francisco, where she feels like an outsider. Worse, her mother has become depressed, and Jody worries she and her sister will have to go to an orphanage. With Happy by her side, Jody hatches a brave plan to keep the family safe ... Will Operation: Happy see them through?
