In a sequel to indie phenom Peter Cawdron's Retrograde, Reentry applies realistic technology to examine not just interstellar exploration, but the dangerous potential of Artificial Intelligence. For fans of hard science fiction by authors such as Andy Weir, Gregory Benford, and Philip K. Dick

After almost dying on Mars, astronaut Liz Anderson returns to Earth, but not to a hero's welcome. America is in turmoil. The war is over, but the insurgency has just begun. So while life on Mars may have been deadly, at least up there she knew who the enemy was. Along with her, Liz has brought the remnants of the artificial intelligence that waged war on two planets. Buried somewhere deep within the cold electronic circuits lies the last vestiges of her dead partner Jianyu. Liz is torn, unsure whether he's somehow still alive in electronic form or just a ploy by an adversary that will go to any length to win. Heartbroken and treated with suspicion, she finds herself caught up in the guerrilla war being waged on Earth, wondering if the AI threat is truly gone, or if it has only just begun.
