Carnelians HC by Catherine Asaro
- Two emperors navigate an uneasy peace, while a powerful trader guild does everything in its power to bring on war. And as if Kelric, the Skolian Imperator, didn't have enough problems, his own brother who happens to be a rock star of galactic proportions has a hit song that calls the traders out as the hidebound blueblood jerks they are, and pleads for an end to centuries of war. Kelric and his Eubian Trader Empire counterpart, Jabriol, attempt finally to meet in a public summit and sign a treaty that will save billions of lives and end the grinding, millennium-long war. But assassins lurk everywhere, and intrigue is afoot as the baroque old order has no intention of giving up its war-bought privilege and power without a fight to the death and they don't care if they take the rest of galactic civilization down with them!
