If you ask me now, I would say that I am currently reading Sherlock Holmes volume 1. (I accidentally bought, then read, volume 2 first.) But in reality, I haven't picked it up in forever.
The reason is...I am currently on the chapter called "The Final Problem" at the part where Sherlock and Watson are hiding from Moriarty by travelling all over Europe. I already know what's going to happen and it depresses me to think about it so I haven't been able to finish the story.
The other issue is, I just can't start a new book if I'm not able to finish my current one. Which means I've basically been stuck in reading limbo for over a year now.
There's so much of the book left to read but I just can't. :'(
