I am one of those people who, when hearing about domestic abuse, ask "why can't she/he just leave"?
There are plenty of books out there describing the abuse itself, but very little in the terms of the reasoning or history behind it. This book, however short, manages to encompass not only the dynamics but each individual history, the reasoning, the emotions of both men involved. It even explains "but I love him/her" excuse most victims use to stay with the very person who treats them like crap. In the end, while hating Sky suffering, I felt sorry for Tate the Abuser. Really sorry, as in "please, let there be a sequel and may he find someone who will set him free".
