I'm crazy lately about reading challenges, and I plan to take part in few starting next year. I'm mainly interested in world literature challenges. Maybe fantasy/sf too.
In my craze I decided to make my own challenge. The A to Z 2014 World Books Challenge. Every month I'll post rules to select (at least) 2 books from various countries. Everybody will be able to choose whatever books they want to read (as long as they comply with the rules). It starts on 1st January 2014, but you can join anytime. More details in the linked post.
