It's a down to earth practical guide aimed at someone who hasn't been to prison before. The ToC features such chapters as Sharing A Cell, Violence, Getting Stuff Done (Complaints and Applications and so on. Smoking teabags, making toast using the radiator, cooking noodles in the kettle, making rope out of sheets to pass things between cells, flash-distilling vodka using ice cubes and a live 240v mains cable, it's all in there.
I highly recommend it to anyone who has ever wondered what prison really involves, day to day, from a prisoners point of view. Or anyone really. It's a fascinating document, very much DIY, reads a bit like a txtfile from back in the day.
