Duchess - Greatcoat is our next book club book, is it not so great?! (pardon the pun)
Worst for me by a long shot - Simon Cowells autobiography. Painful in the extreme. Only read it because it was book club and I hate not finishing a book, even one that bad!
Also could not stand One Day... ugh, what utter drivel and contrived tripe! I read it at the beginning of the year, nearly 10 months ago and its awfulness still troubles me.
I also read BIGTS, wasn't particularly impressed, but it wasn't as bad as the two above, so doesn't quite make "worst this year"....
Ditto When God was a Rabbit. Great expectations, spectacularly dashed.
Haven't read the slap, but also have not heard a good thing about it.
