The guy who wrote it is from Britain and has no affiliation with Eminem which cuts out any chance of any bias creeping in which happens a bit with Anthony Bozza's 'Whatever You Say I Am' as he knew Em.
The book really get's inside Em's head and give's a good insight into his life. The author does his research very well even going to Detroit and talking to Em's primary school teachers and shit. He refernces hundreds of different interviews which give us a good idea of what a mixed up genius he was around 2001-ish.
It goes up all the way to just after Encore and I'd definitely recommend it - that's if you lot are into reading though..
Although I'm sure the Stans will buy it regardless of whether they've ever even seen a book..
