Ghost in the genome. The Exoplanet Survey, #4

When a rogue asteroid is warped onto a collision course with the planet Atlantis, it takes the heroic sacrifice of a brilliant AI pilot to prevent an extinction-level event. For Admiral Sandy Stewart and the crew of the newly christened Huntress, this act of violence by the arrogant Helios triggers a journey that will rewrite the history of the stars. As the crew bridges the gap between the "lost children" of Atlantis and the weary Selene Federation, a shocking scientific revelation emerges: Humans, Atlanteans, Selene, and Helios share more than just the stars.
They share a genetic signature. All four species are revealed to be engineered variants of a single master template, authored by a progenitor civilisation from the Sirius system. From the psychological battlefields of the Trappist system to a tense diplomatic showdown at Helios Prime, Stewart must navigate the legends of the "Dawn Caller" while uncovering the truth of humanity's "Makers". But as the fleet reaches the ancestral home of Sirius, they find no gods, only a haunting, sterilised world where life has been systematically erased.
Now, under the strictest biohazard protocols, the crew must solve the ultimate mystery: why did the Creators vanish, and what lethal legacy did they leave behind in the genome of their children?
