Yoon Ha Lee’s debut novel Ninefox Gambit was one of the most acclaimed SF novels of 2016, nominated for both the Hugo and Nebula awards, and its sequel, Raven Stratagem, is one of the most highly anticipated books of 2017. It arrives in paperback from Solaris next month,

Captain Kel Cheris is possessed by a long-dead traitor general. Together they must face the rivalries of the hexarchate and a potentially devastating invasion.

When the hexarchate’s gifted young captain Kel Cheris summoned the ghost of the long-dead General Shuos Jedao to help her put down a rebellion, she didn’t reckon on his breaking free of centuries of imprisonment – and possessing her.

Even worse, the enemy Hafn are invading, and Jedao takes over General Kel Khiruev’s fleet, which was tasked with stopping them. Only one of Khiruev’s subordinates, Lieutenant Colonel Kel Brezan, seems to be able to resist the influence of the brilliant but psychotic Jedao.

Jedao claims to be interested in defending the hexarchate, but can Khiruev or Brezan trust him? For that matter, will the hexarchate’s masters wipe out the entire fleet to destroy the rogue general?

Both novels are set in the world of the hexarchate, also the setting for over half a dozen of Lee’s short stories, most of which can be read online. Raven Stratagem will be published by Solaris on June 13, 2017. It is 400 pages, priced at $9.99 in paperback and $6.99 for the digital edition. The cover is by Chris Moore.
