Can you add the option to retrieve metadata from www.wlnupdates.com or www.novelupdates.com ?
So that the saved epubs can have all the metadata fields compiled.

This would require creating meta sources much akin to the current sources.
Plus creating a new action so that it can be used without affecting the current usage. Something like

actions:
  ...
  --meta META   url to retrieve additional meta information

Below is a list of meta fields

General

• Description/Synopsis
  synopsis can be taken directly from the website from almost all sites

• Genre/Tags
  tracking sites such as www.novelupdates.com does have a better collection of tags

• Original Language
  for translated work it certainly is a worthy addition

• Year (of release)
  for the spirit of completion

Variable

• Ratings
  this is a very variable value so I don't think its worth

Unique

• fanfiction
  the name of the original work is certainly something that could be included

What are your thoughts?

We just need to get all the epub metadata. Here is a real world example:

<dc:identifier id="book-id" opf:scheme="ISBN">1234567890X</dc:identifier>

    <dc:title id="original">斗破苍穹</dc:title>
    <meta refines="#original" property="title-type">original title</meta>

All the metadata in the example above is taken from Novelupdates.
An extensive API is provided on both websites. You can check wlnupdates.com API here:

https://github.com/fake-name/wlnupdates/blob/master/app/templates/api-docs.md

That makes things a whole lot easier.

It seems novelupdates does not have an api

    <dc:synopsis>With the rising tide of steam power and machinery, who can come close to being a Beyonder? Shrouded in the fog of history and darkness, who or what is the lurking evil that murmurs into our ears?&#13; Waking up to be faced with a string of mysteries, Zhou Mingrui finds himself reincarnated as Klein Moretti in an alternate Victorian era world where he sees a world filled with machinery, cannons, dreadnoughts, airships, difference machines, as well as Potions, Divination, Hexes, Tarot Cards, Sealed Artifacts… &#13; The Light continues to shine but mystery has never gone far. Follow Klein as he finds himself entangled with the Churches of the world—both orthodox and unorthodox—while he slowly develops newfound powers thanks to the Beyonder potions.&#13; Like the corresponding tarot card, The Fool, which is numbered 0—a number of unlimited potential—this is the legend of "The Fool."</dc:synopsis>
