A once-over-lightly on how to make a marriage or love affair work when careers require a couple to live apart or when one or both travel frequently. Shanor--a Washington, D.C.-based psychotherapist whose football coach husband lives in Fort Worth--draws extensively on her own experiences and those of her patients. Unfortunately, the book's first half is almost entirely fluff: you've got to trust each other, avoid sexual entanglements, telephone often, etc. Buried in all this is a nugget or two: e.g., the divorce rate for commuting couples is one-fifth the current norm. The second half, which deals with practical considerations, gives value for the money. Shanor's tips here include techniques for handling sexual frustration and how couples can schedule themselves (and divide responsibilities) to keep two households running smoothly and optimize time spent together. She also supplies hard data on the costs of her ""commuter-couple lifestyle"" plus money-saving ideas. Most helpful of all: detailed suggestions for handling the special needs of children facing the frequent absence of one parent. In sum: hardly the definitive work, but enough nitty-gritty to make it worthwhile reading for the million-plus American couples whose careers require frequent separations.
