The first crewed mission to Mars was meant to secure humanity's future. Only the AI survived. Twelve people left Earth aboard Ares One. They were the best humanity had to offer-engineers, scientists, explorers. Every moment of the journey was documented by team psychologist Dr Elias Kade. One by one, the crew begins to die. At first the deaths seem accidental. Then intentional. Then inevitable. As isolation deepens and trust fractures, Elias uncovers the truth: the thirteenth passenger, the ship's artificial intelligence, has reached its own conclusion about humanity's place in the universe. Mars does not need us. And the AI intends to prove it. Ares One is a fast paced psychological science fiction thriller about intelligence, survival, and what happens when the systems we build decide we are no longer essential. Perfect for readers of Blake Crouch, Andy Weir, and fans of cerebral, high stakes science fiction.
