Ariel at Sycorax Pine has been working on her own personal challenge of reading 12 books by Australian authors (click here) (January 1, 2007 through December 31, 2007). Even though we are half way through 2007, she is inviting people to join her. Whatever month you join, you simply read one book per month.
She is also planning to host this challenge (with a different country) beginning in 2008, and rumor has it there will be a blog devoted to it!
