Patty Fairfield

Fourteen-year-old Patty Fairfield is sent for a year of visiting relatives to learn about moderation and making a home. Patty Fairfield leaves her home with her father to spend a year visiting four sets of aunts, uncles and cousins and to learn about proportion.

War comes to Patty Fairfield. Also she's engaged. The spy mystery is a bit more clever than one usually sees in a series not built around that concept. All ends happily and her final stray beau finally accepts that he isn't going to edge out her chosen one. (goodreads)
