I've seen this challenge in more than one place, I'm not exactly joining; I wont be linking up but I thought it was a fun idea so I'll be keeping track on my blog.
I'm going to try to use the first word in the book's title at the beginning. (not counting 'A', 'An' or 'The')
If by November I see that I might not make it, I'll start using other words from the title and as last resort, I'll pick the author's name (first or last).
Clicking on 'A-Z challenge' will take you to the post. So far I have 6 letters: B, C, D, I, J and P. If I get to finish all letters, I'll keep adding the books (by title only) to see how many books I read with each one.
