My parents went through a divorce when I was 10 (I'm in my 20s now) and the funny thing was that I was much relieved at the time because my father was a little abusive and living around him was like spending each day holding my breath. Short-term (5-7 years) result was that everybody's lives seemed improved from the divorce. But I have noticed, in trying to move on to adulthood, that maybe the divorce had worse effects than anyone realized at the time. Don't get me wrong; I am still glad that I didn't have to spend the rest of my childhood living with my father--- and we did develop a much better, much more reasonable relationship after he moved out of the house.
But the funny thing is that now that i'm an adult (or at least supposed to be one by any standards), i've started noticing differences between me and my friends who grew up in happier, more stable environments. Still trying to define it, but i am hoping this book may help. It is not something that i ever really expected to trouble me as an adult, but it seems worth taking a look at.
