In a new Cold War between Earth and the colonies on Mars, when devastating weapons go missing, there’s only one team you can call – the Outriders.
A fully-autonomous vessel with orbital strike capabilities disappears, and it’s up to Captain Lincoln Suh and his team of death-proofed soldiers to track the untrackable. But when the trail leads them to the isolated and influential Martian People’s Collective Republic, their mission shifts from finding a missing ship to preventing the first interplanetary war.
