I really can't say it was my favourite book of last year, because I am still working my way through it and gaining from it as we speak, standing in the year 2021. If you were looking for a page turner, this one is not for you. I was kind of in the middle of a life crisis (going through a huge period grief, still grieving, and all the while life kept throwing shit balls at me...)....
