Two enemies. One dying planet. Dr. Elias Thorne was supposed to rot in a prison cell. Instead, he's been assigned to Vaxen—a Kaelar Commander with skin like shifting starlight and a heart made of ice. Their mission is simple: save the terraforming project on Xylos-4 or die in the attempt. But Xylos-4 is a world of electric forests and toxic beauty, and the "Static Pollen" in the air is doing strange things to Elias's self-control. When a routine neural sync goes wrong, Elias and Vaxen find themselves tethered by a Catalyst Bond—a rare, forbidden biological link that turns every touch into a chemical explosion. Vaxen's people prize logic above all, but as the planet collapses around them, the Commander must choose: his standing in the empire, or the human scientist who has set his blood on fire.
