Half-book

What do you do when you’re about halfway through a book and you’re not really interested in continuing because the story’s not that great for whatever reason (in my case, it’s the self-absorption and annoying-ness of the main character) but you feel like you can’t cop out and abandon it after dedicating so much time to it already?

I want to stop reading this novel but I feel like I owe it to myself (and the novel, to some extent) to finish it. At the same time, this isn’t a book that makes me want to keep reading or that leaves me itching to find out what’s going to happen next.

What would you do?
