Option A: Read authors A to Z. Commit to reading 26 books theoretically speaking.
Option B: Read titles A to Z. Commit to reading 26 books theoretically speaking.
Option C: Read both authors A to Z and titles A to Z (52 books; this is the challenge Joy created)
Option D: Read internationally A to Z (books representing 26 different countries) (The books could be from international authors (writers from that country); however, it's fine if a book is only set in that country. If need be, instead of countries one could use cities, states, regions, etc. The idea is to use proper place names. If you'd like you could even use a few fictional countries.)
Option E: Read 26 Alphabet books. Embrace your inner child and go visit the children's section!
I'm going to try for option C, authors and titles. I think X,Y and Z will be the real challenge, but i'll do my best!
