This book was... SO GOOD...but also so long. You're essentially buying a book to read three times over the course of reading it once. The format is given in the form of a basal book "the ship of theseus" which you read first. It's quite good and well written, while giving some personal reflection. You then go back to the beginning and get into the "S." part of the book. You read the notes in the margins to get a hold on the two main characters. I definitely recommend, but you need time to read this.
