I saw this and it made me think that there are words out there in the reading world that just have to be shared. I understand both of these definitions so very well. I often read books in one or two settings. That is something as a book blogger and reviewer that is part of my routine.
I definitely feel the first one more then the second one for sure. I get a lot of great books to read and once I am done because I have to know what happens in the story right a way. Then I am like oh no the next book does not come out for months. I sit for a moment and take in that feeling and know that it is my own fault, but I usually have 20 or 30 books on my TBR at any given time.
