I thought 'UnSouled' would come in at around 400 pages, but it took 650 pages, and even then I felt like I was rushing the conclusion, so I asked my editor and publisher if I could divide it again. So a sequel became a trilogy, and the trilogy became a tetralogy - although we're not calling it that.

American Author

Tom King

If you actually read the 'New Gods' tetralogy, this epic without an ending, it's like dipping your head into madness. You feel a little bit like the Joker for a little while. And I mean that in the best way possible.

Originally used in ancient Greek literature for a set of four works.

Literary Origin

Common in literature and arts, signifying a complete series.

Cultural Works

The works in a tetralogy are often connected by themes or characters.

Unified Themes

In medical context, it’s a set of four symptoms defining a particular condition.
