This book is everything a memoir should be, and it's clear why it's been raved about since its release. 
The style is excellent. The writing is witty, charming, and relatable. Reading Jeanette's experience as a child, and all of her thoughts about what she was experiencing, reads as genuine and authentic (and I loathe when adult-writing-in-child's-voice is done wrong). 
My only issue with this book is that at times the pacing feels awkward; I found myself wondering about specific happenings between time-jumps and questioning why so much time was spent on other moments, but these did not detract much from the quality of the book.
