So, I think I've closed my challenges by now. 9/10 are about books, 1 is about culture in general.
3 out of 10 are made by me:
- A to Z 2014 World Books Challenge - reading books from different countries.
- World Culture challenge - getting deeper into various aspects of culture.
- In 16 Books Around Poland (for Polish book forum) - reading 1 book about each of the provinces in Poland.
If you still haven't decided on joining a challenge, check out the challenges I take part in. More info here: http://forculturessake.wordpress.com/challenges/
