If you are on page “example.com/2016/09/22/my-novel-chapter-23” and there is also a page with slug “my-novel-chapter-22” then previous chapter link would be added. If there is page “my-novel-chapter-24” next chapter link would be added too.
Pages and posts wouldnt be associated to each other even if they have similar slugs. Pages would be associated with pages and posts with posts. Works with both pages and posts, permalink structre doesnt mather as long as your slug ends with hyphen followed by chapter number.
Example:
<ul>
<li>example.com/2016/09/22/my-novel-chapter-23</li>
<li>example.com/my-novel-chapter-23</li>
<li>example.com/my-novel-index/my-novel-23</li>
</ul>

Using this widget you can easily place the Cool-er Ruby containing an image of the cover of the book you are reading in the sidebar. You can also specify a URL to link to when clicking on the book cover image. Supports multiple instances, so you can use it multiple times in multiple sidebars. (adapted from the Simple Image Widget)
Once the plugin is enabled, the widget will be available in your widgets list as “Cool-er Ruby Widget”. You can add this widget to sidebars as many times as you need. The control interface allows you to specify the following options for each instance of the widget:
<ul>
<li>Image URL: The full URL to the image file</li>
<li>Alternate Text: Shown by the browser if image cannot be displayed</li>
<li>Link URL: URL to open when the book cover image is clicked on (optional)</li>
<li>Open link in new window: If this is checked, the above link URL will open in a new browser window</li>
</ul>
