Thomas, an investigative journalist, puts two divorces under the memoirist's microscope — her parents' and her own — and thinks about how the former led to the latter. Thomas' deeply felt prose and pitilessly intelligent self-analysis raise her story to something on the order of a generational anthem (which, as Gen X enters middle age, it sorely needs). If you've been through the pain of a divorce or watched one at close range, you may recognize emotions here that you've never seen written down anywhere else. 7/12
