I'm currently reading Open City by Teju Cole. And I like it. It isn't the best book I have ever read, but it is not bad. Not bad at all. I am about 3/4 of the way through and nothing is compelling me to finish. I don't need to find out "what happens." I don't need to know where everyone goes. I am happy with the book as is.
Should I finish it?
I never would have asked this question before I read the article I link to above.
I think it is perfectly acceptable to toss away books that you don't like. The Help being one of the best examples in recent memory. I don't care how many people liked it. I refused ... flat out refused to read past page 30. I could not stand it. Close it. Set it aside. Pick up something worthwhile.
Open City has been worthwhile. But I kind of feel I have had enough. Not in a bad way. Just content with what I know about it today.
And if you don't finish it by choice, do you get to put it on your books of the month/year lists?
