My OH tells me off for reading the back of a book before I read it.   So no spolier links allowed --

I always do that - my husband thinks it's an odd thing to do too.
I do it too, but its much harder to do with a Kindle, (which I use when travelling)
My justification is that, if I am getting bored with the book, reading the last chapter gives me the incentive to continue! 
I am looking fro ward to tonight's episode  even having read the spoiler!
