To start, I want to recognize that this must have been an extremely difficult book for Sandberg to write. I commend her bravery and openness in sharing her story.
I did not, however, like the format of this book. While I think it would have been fine as a single-authored memoir or guide book on dealing with grief/adversity, the mix of the two did not sit well with me. It was too jarring to flip repeatedly from personal passages detailing Sandberg's unimaginable loss to dry, clinical summaries of scientific studies about grief.
By the end of the book, I was left wanting to read a more traditional memoir authored only by Sandberg.
