You probably want the updated version, which is about 3x as long and includes the next 2 sequels. Amazon has told me they have notified purchasers that an update is available, but if you haven’t received it, you need to enable automatic book updates on your kindle.
- Login here: https://www.amazon.com/mn/dcw/myx.html
- Click the “settings” tab
- Scroll down until you see “automatic book updates”
- Toggle it on.
You should then automatically get the latest version of the book when your Kindle is next online.
