Ghostopolis is a graphic novel, written and penciled by Doug TenNapel, colored by Ethan Nicolle and published by GRAPHIX, a Scholastic Inc. imprint.

The story revolves around two main characters: Garth Hale, a young teenage boy, and Frank Gallows, a middle-aged agent of the Supernatural Immigration Task Force, a government partition dedicated to locating ghosts amiss in the physical world and transporting them back to the afterlife (here known as the title Ghostopolis).

On a routine call to remove a Nightmare (a skeletal horse of the afterlife), Frank accidentally ports Garth to Ghostopolis along with the spectre.

In Ghostopolis, Garth unintentionally tames and befriends the Nightmare, nicknaming him "Skinny" due to the horse's incorporeal appearance.

Narrowly escaping an attack by several Velociraptor skeletons, Garth determines that his best course of action is to venture into the main city.

Meanwhile, Frank is fired from his position on the Task Force for his grievous mistake and instead enlists his ghost ex-fiancée, Claire Voyant, to assist him in traveling to Ghostopolis and retrieving Garth.

It's hard to say how long it took since time is all jumbled up in Ghostopolis.Now, however, a malevolent character named Vaugner currently rules over Ghostopolis and its inhabitants.

Suddenly, a Supernatural Immigration Task Force extraction team from Earth appears and attempts to collect Garth.

Vaugner returns, apparently unharmed, and sends the team's ship back to Earth without Frank, Garth, and Claire.

In the midst of the celebration, Garth meets his anachronistically-aged son — this is attributed to the numerous time inconsistencies in the realm of Ghostopolis.

The graphic novel ends with Cecil, now an aged ghost in the physical realm, flying into the nighttime sky, having apparently made peace with his daughter.

In 2009 a film adaptation was announced, with Hugh Jackman attached to star and produce under his own company Seed Productions, with both the Gotham Group and Disney.
