After a heart-rending discovery of Norbett spending time with another girl, Beany is delighted to have an opportunity to go away on a road trip to California with her brother Johnny and her little nephew. Tight finances and a favor to a friend cause the trip to become harried with a whole array of fellow-travelers (and a horse). Kindly, motherly Miss Opal doesn't have money, but performs near-miraculous feats of producing food and lodging out of thin air (not to mention her tomato plant in the back seat). Cynthia forces herself upon the group through kind-hearted Johnny.

Robb White brings us an exciting historical fiction tale of life aboard a military submarine in the Pacific in World War II. Someone's been transmitting top-secret plans from the American base in Hawaii to Tokyo. The Americans have learned that transmissions are being sent from Hawaii to an island in the mid-Pacific and from there to Japan. They believe they've located the island where the transmissions are being passed along, but have been unable to break the special code being used there.

Beany now sixteen, is a junior and busy with the school paper. More than anything else she wants the editor to pick her to go the school paper convention. Norbett Rhodes has moved to Ohio and suggested that Beany could date others. Devastated at first, Beany has made friends with Andy Kern who thoughtfully likes to keep things light (in the dating department). After promising her nice mother, Beany reluctantly befriends a new girl at school, Dulcie, who is a showoff and very flirtatious with the boys.
