BOOM! Studios has announced Royden Lepp’s Rust Vol. 4: Soul in the Machine, the final chapter to his critically acclaimed graphic novel series about a mysterious boy who suddenly appears on a farm struggling to survive after a long apocalyptic war and changes the fate of the family who runs it. Debuting in February 2018, this original graphic novel marks the first time the publisher has released both hardcover and softcover editions simultaneously in comic shops and bookstores.

At the center of the Rust saga is Jet Jones, a boy with a jetpack who crashes into the Taylor family farm. As Jet deals with his uncertain future, members of the Taylor family each view his arrival—and subsequent stay—in different ways.

Developed over the last seven years, Rust is a deeply personal story that echoes Lepp’s own history—in particular, the eldest son, Roman, who grapples with the loss of his father, who went missing during the war.

The previous volumes of this acclaimed graphic novel series—Rust Vol 1: Visitor in the Field, Rust Vol. 2: Secrets of the Cell, and Rust Vol. 3: Death of the Rocket Boy—are all available in hardcover, softcover, and digital format. An additional release, the Rust Vol. 0: The Boy Soldier softcover, collects the prologues of all four hardcover volumes.
