Funny you should bring this thread back from the dead. Was just about to resurrect it myself.
I read Screwed over the course of last week. It's about a prison warden who gives you an insight how the prison system works and tells a few funny tales along the way. Wasn't anything amazing, shoved in a few hours commute and reminded me very much of reading 'Bloody Casuals'. Easy to read though and reminds you, if you ever needed it, how over-PC it's became in the UK.
As always, if you want the book, PM me your address.
