Astraeus, by Callan J. Mulligan, is a bestselling scifi thriller for fans of James S.A Corey's The Expanse, Alex Garland's Sunshine, Isaac Asimov's Foundation, and the like.

Onboard a world-settling starship named The Astraeus, a colony adjusts to their new life in the stars as they embark on a two hundred year journey to the centre of the Milky Way. 

Senator Cassian Abner wishes to build a new world but finds himself at odds with the ship's government and crew. Lizabeth Denning is a daughter of wealth, using the Astraeus as a refuge from her troubled past. Carron Riddell is a young engineer, responsible for maintaining the crucial machines that keep the mission alive. Jim Atley is a stowaway, running from a deadly secret that is bound to catch up with him. 

The Astraeus is a paradise, but their utopia doesn't last long. When a passenger is murdered, the colony begins to turn on each other, and things get far worse when the ship begins to experience violent tremors. 

In a race against time, they must find answers and repair the damage or risk falling victims to the cold empty void of space...
