This plugin helps you create a series of posts. It creates a new taxonomy named ‘series’ (can be modified via filter, see FAQ). There is no setting needed for this plugin. Once it is installed, assign posts you want to group as a series via post editor.
The plugin also creates a posts navigation on posts that belong to a certain series. See screenshots for the examples.

Works beautifully and doesn't have a sucking frontend design, as other similar plugins do!

Very good!
