I used to read Nikki Gemmell's journalistic musings, until I gave up on the publication she write for, but up until then she was one of the reasons for continuing to read it.
Here, she tackles the topic of quiet, in a personal, sometimes style and much personal information about her life and family and various related issues. I think she sets her standards of self too high here, but I'm not a mother or a parent and I haven't experienced the kind of family life that surrounds her. Having said that, some of her presumptions about mothers and children may not be as universal as she thinks, from my observation and reading, anyway.
She admits to shyness in a way that makes sense to me (introversion is a separate issue of course) and there are the usual things about space and noise.
This is a slim text, the size of a hand (someone's anyway) and part of a series of similarly sized musings, and probably could be read in an hour or two; I read it in two sittings a month apart, no reflection on the book, just my idiosyncrasies as a reader. It's a thoughtful book, well written and quiet in a particular way, even though it doesn't appear to have been written for people like me.
