He didn't choose to be tribute. He didn't choose the General. He didn't choose any of this. But the Varreth don't negotiate. And biology doesn't ask permission. When Earth's treaty with the Varreth Empire requires human tributes, field medic Callum Reid finds himself assigned to the most feared General in the Third Fleet. He expected a cell. He got a suite with no lock on the connecting door—and a seven-foot alien warlord who looks at him like he's already been decided on. General Soren Varreth-Kael has commanded fleets, faced emperors, and chosen war over connection for two hundred years. Then Callum walks off the transport and Soren's biology does something it hasn't done in two centuries. He knows exactly what it means. He tells no one. Soren could claim him. The bond demands it. His empire expects it. But Soren wants something the Varreth bonding law doesn't require and has never needed before—he wants Callum to choose it. So he waits. And Callum, who catalogued every exit on the flagship in the first week, who sat in front of a comm terminal for an hour and didn't message home, who told himself the pull was proximity and biology and nothing personal—starts to run out of reasons to leave. The Emperor isn't patient. The resonance isn't invisible. And Callum is starting to understand that the unlocked door was never about the General's access to his room. Seventy-two hours. One choice. And a future that belongs to neither of their worlds.
