Timboli: you seem to be making this hard work for yourself. Let me tell you how I do this:

I either download a book from Amazon, or if from another site like mobileread I download the epub version onto my computer.

I then open this with Calibre, using the right click Open With option. In Calibre, I click the Edit Metadata icon, then ensure that the name and author name are correct, then click Download Metadata. This looks for a description of the book from Google, Amazon, and several other sites. I then have a list of sources, click on them, choose the description I like most, then click OK.
I then have the option to change the cover from a boring PG to something pretty. Calibre fetches covers and I click my prefered option. I like to see a cover when I open the book, I have the kindle set to list display.

I then convert to azw3, so that I can use custom fonts. To get the description at the beginning of the book go to Structure Detection in the Calibre conversion box, then click Add Metadata to Beginning of Book. When this has finished I view the outcome and put the resulting azw3 file into a "New Books" folder on my hard drive. This will be put onto the reader and into a collection when I'm next charging the reader.

Or you could leave the book in Calibre (it's there anyway) and just directly sideload into the ereader while charging.

Result: a book, with description, in a format of your choice.

I do far less fussing around finding something to read; it's a matter of mood. For example, I'm just finishing a very light comedy and fancy something more substantial next. Just took me a few moments to find H.G. Wells, The Invisible Man in the Classics Collection; seems like a good antidote to so much silliness.
