We say book, you say buk 
Hi Caroline
The only two Southeners who refer to a 'book' as 'buk' are the Queen and Hyacinth Bucket pronounced "Bouquet". But in every Southener lurks a little Hyacinth, even if only in the little finger one raises pependicular when sipping, usually Earl Grey, from a cup. Of course in the North you have your big mugs of Yorkshire tea to slurp from which double up as a face wash to remove all the grime which continues to float in the atmosphere from the once successful industrial towns/coal mines.
The North has three redeeming qualities:
Landscape/areas of natural beauty
Manchester United Football Club
The Smiths/Morrisey
