Why yes, my TBR does yell at me periodically. Doesn't yours?
So why did I keep reading? Because I felt like it was way too late to turn back. I was already invested. This was a three hour book (that took me two weeks to read, by the way) and I was at the hour mark. That would be like me running a marathon and then just quitting at the 24 mile marker. (FYI, if you ever see me running then you should run too because someone is probably chasing me.)
So my question is this: at what point do you decide to DNF a book? Is there a "point of no return" when you feel like you have to finish it, no matter what?
