When Cold Suns Burn

Two cousins, taken as children to be made into instruments — Alex, who can walk into any room and know it to the bone; Sylvan, who can read a page of figures and tell you which of them are people.

Their species has been found, and cannot run. So it does the only thing left to it: it reaches out, across distances that swallow lifetimes, for the two peoples who once escaped the same fate — driven from the galaxy long ago, scattered to the dark between other stars, and still, perhaps, able to remember how to help.

The cousins are sent to carry that reach. On separate ships and separate clocks, close enough to speak across the light-years and never close enough to touch, they drift apart in age with every year that passes in isolation — until the cousin at the far end of the line is a stranger who has quietly become the older man.

And the thing the galaxy has feared in silence for a million years — a weapon that empties worlds, and the ancient, patient order that decides when it is used — has been waiting for them since the start of the crossing. They will reach what they were sent to reach. It is what comes after the reaching that none of them was built for — and that will ask a small, wronged people to decide, in front of the whole watching galaxy, exactly what it is willing to become.

When Cold Suns Burn is the devastating conclusion of The Quiet Threshold — a saga of first contact, deep time, and the terrible arithmetic of love.
