I will try to explain clearly what I would like to do:
On Kindles you have about this book in the menu, when you click this it takes you to Amazon and you can view the synopsis of the book.
I don't want to connect my Kindle to the internet and I load all of my books onto it through Calibre connecting via a USB cable so I was wondering is there a way of loading a synopsis into the book itself using Calibre?
I have a synopsis/ plot summary written for each of my books under comments in Calibre but I was wondering if there is a way too add/ copy this info to the book file itself so it can be accessed when on the Kindle?
I tend to load a few books at a time onto my Kindle so by the time I get to them I've forgotten what the book is about

having a summary/ synopsis available in book would be a great help.
I did try just adding a new page to a book using book editor with the synopsis on it but I didn't really know what I was doing and I couldn't get the new page to show up in the table of contents or anything so wasn't accessible when reading unless you manually scrolled back through the book.
If there was a plugin for this or some way of doing it that would be great
If this post doesn't make sense I will try to clarify what I'm after
