"The successor to The Risen Empire is just as fine a rip-roaring space opera"—from the #1 New York Times–bestselling author ( Booklist). Captain Laurent Zai of the Imperial frigate Lynx is a walking dead man. Unjustly held responsible for the death of the Child Empress, sister of the immortal Emperor, Zai has been sent to fight an unwinnable battle. The Lynx must stop a vastly superior Rix ship from reaching the planet Legis, a suicide mission that will almost certainly end in oblivion for Captain Zai and his crew. On the planet Legis below, a Rix compound mind—a massive emergent AI formed from every computer on the planet—has been isolated by their Imperial blockade. But the mind has guided a lone Rix commando, Herd, to the planet's frozen north, and will soon order a desperate attempt to seize a polar communications array and break the blockade. Ten light-years away, Captain Zai's true love, the psychic (some say mad) Senator Nara Oxham is engaged in a deadly game of political intrigue. From her position on the Emperor's War Council, Senator Oxham must find a way to forestall the Emperor's final solution if the blockade is broken: a nuclear strike to destroy the compound mind, which will also kill millions of Imperial citizens. She suspects that the Emperor has a hidden weakness discovered by the mind, a secret so dangerous to his immortal dynasty that to prevent its discovery the Emperor is willing to countenance the ultimate crime . . .
