A wry look at the ""Synergistic Family""--which includes residual children from former marriages, children from current marriages, and ex-spouses who don't actually live with the new couple, but who are a constant financial and emotional presence. Author Mayleas' sprightly style and insightful portraits of the problems of the much-married and their extra baggage will provide at least a few crooked grins--and some helpful hints--for those who have been there. Money worries, sex problems (including some juicy ones about step-parents seducing their new spouse's grown children, with disastrous consequences) and, as she puts it, other domestic blessings that are the result of the increasingly common expanded/extended family.
