I now have at least one example for each of the three read statuses:

https://gregorlove.com/2017/12/want-to-read-a-wind/

https://gregorlove.com/2017/12/currently-reading-a-wrinkle-in/

https://gregorlove.com/2017/12/finished-reading-a-wrinkle-in/

With the last one, I realized I could make it a reply to the previous status so they show up as comments and the entire read cycle is linked together.
