No, I haven't read Graeber's book. This was The Grip of Death: A Study of Modern Money, Debt Slavery, and Destructive Economics by Michael Rowbotham. From memory, the title is derived from the literal meaning of the term 'mortgage'.
It wasn't a book that I sought out. I just happened to be traveling at the time and was asked to return it to it's owner, so read it on the plane. I can't remember enough of the specific substance of the book to make a definitive recommendation but I can say that I remember it being very engrossing and will always appreciate that it broadened my interest in economics at the time (coincidentally I had just finished my studies in economics that year).
