A decade ago, explorer Isabella Faye Drake was chosen to take the illustrious and all-important Voyage to hunt down a new Earth. Like the other Voyagers before her, she never returned, leaving behind two sons Hellener and Sebastian, and their father Roderick. When the Ministry of Exploration chooses Hellener for the same deep space mission, his brother Sebastian is left behind to try and contain a depleted Mars that stands on the brink of a civil war. While Hellener chases the fleeting dream of a new home, Sebastian struggles to ensure his brother will have a home left to return to.
