Where are you reading is hosted by Book Journey. I did pretty well this year (for not really aiming for specific states), so am giving it another go.
Witches and Witchcraft Reading Challenge is hosted by Melissa's Eclectic Bookshelf. I will be aiming for the Initiate level (1-5 books).
Audio Book Challenge is hosted by Teresa's Reading Corner. Since I've read over 40 audiobooks this year, I'll be aiming to the Married (listen to more than 25 audiobooks) level.
Mount TBR Reading Challenge is hosted by My Reader's Block. I didn't do too well on this this year, so am going to try again. I'll be aiming for Mount Blanc: Read 24 books from your TBR pile/s.
Historical Tapestry hosts the Historical Fiction Reading Challenge every year for a few years now. I'll be trying it this coming year, at the Renaissance Reader level (10 books).
That's it for right now. Will probably look out for a library challenge also.
