The Perfect Nanny by Leila Slimani

Not a book for working moms with a nanny!  It's terrifying....and based on that true story of a nanny in NYC who murdered the kids.  I remember that so well.
The book must be critiqued then by its style, its language, the way it builds the character of Louise, this "perfect nanny" who we try to understand.
I can see why it's such a best seller, and I can also see why it won a big award in France when it was released.
But would I recommend it to a young mom with a nanny?  NO!
