A Short History of Nearly Everything discussion

Help! After changing the status of my last book from Currently Reading to Read I noticed that my Currently Reading 'score' was -1. Que?? I then marked a new book as Currently Reading and the score changed from -1 to 0. Not sure if that's worrying or awesome!

I suspect it may be something to do with the fact that I started reading one version of my last book but finished reading a different version, which I had purchased. I deleted the old version from My Books to avoid a duplication but maybe I confused the system. Hey, did I break Goodreads??

definitely odd, maybe the -1 means the book was wiped from your memory

What book?? :-D
