The Last Contract of Isako

by Fonda Lee

A battle-worn corporate samurai undertakes one last mission on a merciless planet where death is always a mere breath away, in this standalone dystopian epic from the author of the modern fantasy classic Jade City. 

LIVE BY THE CODE. DIE BY THE KNIFE.

Isako is a legendary swordswoman, but every legend must come to an end. When her long-time client unexpectedly retires, she plans to follow—to walk out into the frozen wasteland of their planet with her head held high and her family enriched by her death. But when she's offered a final mission, she can't refuse, especially when she realizes who lies at the center of it Martim, her last—and worst—apprentice, who's somehow made his way to the top. As she's thrust into a world of corporate espionage and shadowy secrets, what she uncovers could forever change humanity's existence among the stars.  

The Last Contract of Isako is epic science fiction like only Fonda Lee can write it—set in a world where money trumps loyalty, the elite have the power to extend life or end it, and one woman in the twilight of her calling must decide what's ultimately worth living—or dying—for.

[Rebecca Roanhorse]

You had me at corporate samurais in space, but add a murder mystery with a surprising twist, effortless worldbuilding on a terraforming colony with a big secret, truly heartfelt characters grappling with duty and honor, and you have a slick space opera that in uniquely Fonda Lee. Fans of The Green Bone Saga are going to eat this up.

Oh she's (Fonda Lee) taking it (my direct deposit as soon as it hits my bank account)!

In the author’s words:

My next novel, The Last Contract of Isako, is a cyberpunk samurai space opera (without the space) that I describe as what you’d get if Akira Kurosawa wrote Dune starring a 50-something give-no-fucks swordswoman on her last job, blended with vibes of Blade Runner plus a touch of John Wick.

The Last Contract of Isako is the cyberpunk samurai space opera that’s been percolating in my brain for years. It’s a science fiction mystery chanbara story set on a harsh Arrakis-style tundra planet but blend in Blade Runner vibes and a touch of John Wick. I’m very much looking forward to introducing readers to Isako.
