Bookworm Blurbs

I'm now having a bit of a harder time getting myself to read this. I'm not sure why. It covers  a subject that is very interesting to me, it's well-researched, it's well-written... and yet, I have to force myself. I think I'm just not in the mood for non-fiction at the moment. I'm trying to decide if I should force myself to read it so I can just be done with it (which might make me enjoy it less than I would), or put it off until I'm more in the mood for non-fiction and risk having to re-read what I've already read. 

Decisions, decisions. What do you all think, fellow booklikes users?
