Gave up at 54% in. Life's too short to put up with books I'm neither enjoying nor the least bit interested in. (Rating-wise, I'm going by the Goodreads' definition of "didn't like it" - it's not like it was, objectively, the most god-awful book ever, but if I can't even bring myself to read the whole thing, "didn't like it" fits.)
It sounded funny from the blurb, but as I've said before, humour is subjective and this specific sort didn't really work for me. At all. I was alternatively bored with and irritated by all the characters and once the plot turned into religious stuff, my interest in that waned, too.
