I'm hopefully coming to the end of an unplanned "reading drought" myself. The last few weeks have been very busy and won't be slowing down any time soon. So a book that should have taken me 4 days maximum has now taken almost 3 weeks (minus the 3 or 4 days it took me to read two novellets also in the series).
I also lowered my challenge, removing the 20 "Bonus" reads requirement. With that, I've now stripped my challenge to the bare minimum, yet I'm still a book or 2 behind for the 65 series books in my main challenge.
At this point, I realize that I probably should have stayed with my first instinct which was 50 books & 150,000 pages.
