From the publisher:

It was inevitable. Our ravenous hunger for resources eventually stripped the Earth dry. Fortunately, our ambitious technology reached the point where we could turn our sights to the stars, which were full of materials to exploit. A New Frontier for a new gold rush.

In this rustic future, three souls eke out a living: Ji-Soo, a scientist with a passion for discovery, Camina, a feisty, battle-scarred mercenary, and Alex, an asteroid miner who has never been to Earth. Through their exhausting daily lives, they each dream individual dreams, following their own road toward that horizon. But when those paths cross, those dreams change trajectory, taking them all in a direction they couldn't have imagined. What will become of humanity when it is completely disconnected from its cradle, the Earth?

Created by artist and author GUILLAUME SINGELIN, FRONTIER is a feature-length snapshot of life in the age of space exploration. Built on a foundation of plausible technology and scientific advancement, FRONTIER explores the new, daily challenges of life in space: from the mundane task of farming to the political strife of corporate trademark and territory claims. Life in space isn't easy… but where else can you go?

Told in a breathtaking visual mashup of cartoony characters within hyper-detailed and expansive environments, FRONTIER is unlike anything you've seen before. Described as "THE EXPANSE or FIREFLY populated by chibi manga characters," this premium 200-page graphic novel builds a sprawling new universe that may one day come true.

Resume:

Quand la Terre suffoque de par l'exploitation de ses dernières ressources, l'humanité se tourne vers un nouveau territoire, l'espace, au-delà des planètes du système solaire : « La Frontière ». Dans cette nouvelle ruée vers l'or, trois destinées s'entremêlent : Ji-soo, scientifique passionnée par l'inconnu ; Camina, mercenaire fougueuse et enjouée ; et Alex, un mineur qui n'a jamais connu la Terre. Ce récit d'aventure narre le parcours tumultueux de ce trio, mais aussi de leur quotidien, celui de vivre dans un nouveau monde. Il pose la question d'une nouvelle humanité complètement déconnectée de son berceau, la Terre, pour se tourner uniquement vers les étoiles.

Guillaume Singelin was born in Rennes, France, and grew up inspired to draw by Disney comics and manga. While studying graphic design at EPSAA, he was approached by writer Antoine Ozanam (KLAW, Temudjin) to work on a retelling of the David and Goliath story in King David, revised to be a contemporary mafia tale. But comics weren't what he originally imagined doing, so he joined the animation team at Ankama to work on the feature film MUTAFUKAZ, based on the Label 619 comic series by Label founder Run. It was during this time Singelin dreamed up The Grocery, a madcap combination of cartoonish characters in a gritty urban setting much like The Wire. That unique recipe found fans, and he soon began contributing more and more work to the growing portfolio of Label 619, including stories for Doggybags, Midnight Tales, and the MFKZ spinoff Loba Loca. His first full-length graphic novel to be published in English was the dense postwar drama PTSD, which not only refined his unique balance of cartoony characters in gritty situations but cemented his reputation for thoughtful and multilayered storytelling. His manga-inspired character designs pop out of realistically rendered environments to come to life. From that experience and exposure, he was tapped by DC to create a handful of Batman backup stories (in Urban Legends and DC Vampires). Aside from comics, he continues to work in other fields, including video games, producing illustration, and character design for titles such as the celebrated multi-platform game Citizen Sleeper.
