Booking Through Thursday: Half

Booking Through Thursday asks:

So … you’re halfway through a book and you’re hating it. It’s boring. It’s trite. It’s badly written. But … you’ve invested all this time to reading the first half.
What do you do? Read the second half? Just to finish out the story? Find out what happens?
Or, cut your losses and dump the second half?

Honestly, I don't tend to read books I don't like.  I'm very selective about my  books.  I read from recommended and award lists.  Mostly I love every book I read.  I certainly won't get through a half of a book before I decide I don't like it -- I'll just put it down and read something else.  Sometimes I get back to a book after some time and I do enjoy it. 

I'll say, there are two books I tried reading multiple times and never got past the first chapter.  One was The Two Towers by J.R.R. Tolkein.  The other was Dune by Frank Herbert.  I am a big science fiction and fantasy reader, so I'm sad I didn't get into these books.  It's been over 10 years now; maybe I'm due to give them another try.
