Yes, it's possible. The month is for the challenge of it. To read and learn and write something about the book in that month. What you write can be a post for Steemit or something you'd like to have published outside of Steem. Anyone is welcome to start whenever they like to, and the deadline isn't hard-set but encouraged.

We do discuss the book sometimes in the channel on The Writers' Block Discord server, but not in-depth so that everyone has a chance to learn from the book without other thoughts and opinions interfering. And to avoid spoilers where possible.
