I think 'The Fallen' will probably be the best book written about The Fall (can you still get 'Hip Priest'?) but the SHanley book is good light reading as long as don't have some irritating woman in the corner asking why you've started playing 'all this tuneless sh1t' again.
'Hip Priest' is for sale on Amazon, £17.19 used or £415.32 new (that the cheaper option new, someone else is selling it for a bit under 4 grand).
