War. Heresy. Madness.

Shuos Jedao is unleashed. The long-dead general, preserved with exotic technologies and resurrected by the hexarchate to put down a heretical insurrection, has possessed the body of gifted young captain Kel Cheris.

Now, General Kel Khiruev’s fleet, racing to the Severed March to stop a fresh incursion by the enemy Hafn, has fallen under Jedao’s sway. Only Khiruev’s aide, Lieutenant Colonel Kel Brezan, appears able to shake off the influence of the brilliant but psychotic Jedao.

The rogue general seems intent on defending the hexarchate, but can Khiruev – or Brezan – trust him? For that matter, can they trust Kel Command, or will their own rulers wipe out the whole swarm to destroy one man?

Yoon Ha Lee’s critically acclaimed Machineries of Empire trilogy continues with Raven Stratagem, coming from Solaris Summer 2017.
