Heard about this on "Brain Pickings" and it is on its way. A good read for boys at bedtime? 9 and 11yrs.
No, I don't recommend it. It's definitely a book for adults. I personally found it had many long boring parts mixed with very interesting ones. Very introspective.
There's some dark stuff in there about her working through her feelings about the death of her father. Probably not suitable for kids.
