I think this might be my favorite of the Tippy series, if only because Tippy really has a chance to grow up and become her own person. She and Peter marry in the first few chapters, then move to his duty station in Panama. Tippy is terribly homesick but tries to look brave, hiding her loneliness and falling into self-pity. Peter, knowing her as he does, is not fooled and has worries of his own.
Family members help Tippy escape her pity-party--one of them involuntarily being helpful!--and Peter demonstrates patience and wisdom--surprise, or not! His nickname for Tippy annoys me no end, but overall he is a solid and likable hero throughout the series, who goes through difficult growth periods of his own.
I found the setting fascinating, and Tippy's maturation from a spoiled and self-centered youngest child into a young Army wife who can stand on her own two feet makes for a quick, satisfying read. Don't expect excitement or great drama in most of these books--they're written for young teens and have many strong points of their own.
