@dangillmor Worth noting the Python script, bookp.py, might need the WebDriverWait values tweaking to give you time to tackle the captchas that Amazon have thrown up. My approach was to change them to 15 seconds and and use the --showbrowser parameter, so when it stops on a captcha on login I have time to fill it in. Once you manually push it past the login like this, it works. The version that works for me is the one posted by @mschomm - the original not so much.

@greg_harvey @dangillmor @mschomm Thanks for the tip, Greg. Can you clarify, for a fairly basic Python user, how/where to change the WebDriverWait values in the script? I couldn't figure it out. When I ran bookp.py in the command prompt, I got an uncaught N-API callback exception detected. Following cmd recs, I added --force-node-api-uncaught-exceptions-policy=true, which removed the error but didn't seem to produce anything.
