So far I have read 11 non-fiction books and 9 fiction books (although 4 of those are from the same series).
I am averaging 10 books a month and some of the non-fictions have been whoppers (Cornelius Owen I'm looking at you!).
At this rate I will have finished the 80 book challenge by August and that's not taking into account that my rate will go up whenever there is a school holiday and I am currently studying for the Primal Blueprint Expert Certificate which is taking up most of my non-fiction reading time.
Might have to make the challenge 120 books instead of 80!!
