The Procyon Limit. The Roche Limit Chronicles, #2

Matter is collapsing. Minds are next. At the edge of colonized space, something is rewriting matter itself. When a deep-space anomaly begins converting ordinary matter into an impossible new form, terraforming technician Kalen Thar uncovers evidence that the disaster is spreading faster than anyone predicted. At the same time, an alien species known as the Rahl descends on the system, infiltrating neural networks through harmonic resonance and turning human technology against itself.
Kalen is not a soldier. He's an engineer with an instinct for impossible systems, inherited from his missing physicist mother. His only constant ally is Draxin, a cybernetically enhanced canine whose tactical brilliance is matched only by his sarcasm. As exotic matter destabilizes the laws of physics and the Rahl tighten their grip, survival will demand more than firepower. Kalen and Draxin will have to outthink forces capable of rewriting reality itself.
From collapsing gas giants to the surreal echoes of 1980s pop culture, The Procyon Limit blends hard science fiction, dark humor, and cosmic-scale tension into a fast-moving story where intelligence matters, loyalty has teeth, and some enemies can only be defeated by becoming stranger than they are.
