I'm not yet 50, but this is the most helpful book I have read since I learned my husband was leaving me after almost 26 years of marriage. I wish it had been the first of the books I had read, and that I had read it much sooner in the (ongoing) divorce process, but I probably wasn't in a place to do so at the time. It's a well-organized, practical, detailed guide with emphaiss on finances. It's easy to skim over the parts that don't apply to you as an individual and to find the substance that does.
