Deployment by Ignacio Martín Arano

John has never left the Sol system. After a miserable life on Earth, his first job takes him from Mars to Elysium. It is the first time he has ever left home. A new world awaits him, filled with people, cultures, and places he has only ever heard about. John is about to discover that humanity is only a small part of a much larger galaxy. And for someone who has spent his entire life knowing so little of the world beyond Earth, there is a lot left to discover.
