OVERVIEW/ANALYSIS: When Isako's boss unexpectedly retires, she knows she's at the end of her career. Afterall, what is a longkniveswoman without a contract? But an expected offer comes in from a rival executive for one last job - one that will allow her to retire on her own terms. The contract: successfully find dirt on one of the most powerful executives at the Company and stop him from joining the Board of Directors. But as soon as Isako starts poking around, she starts finding a bigger conspiracy than she anticipated - and all roads lead back to Martim, the last person Isako ever took on as an apprentice.

The Last Contract of Isako is an atmospheric mystery set in a bleak, harsh world that offers little comfort to the reader or those who live in it. By far the highlight of this story is the world-building. The author has created a pressure cooker of a city, where everyone's value is determined by whether or not they're deemed useful to society. Every element of this world boils down to the fact that it is a resource scarce colony. If you aren't contributing to the colony's survival, then you're a drain on resources. But of course, the people who determine what is useful are the elite who will almost never have to face the consequences of the society they've created. And like the frog in the slowly boiling water, the rest of society doesn't realize it's already cooked.

I've found myself calling this a cybernoir book. There's elements of cyberpunk, with one giant corporation controlling everyone's lives, technology integrated into bodies, and a big disparity between the haves and the have nots. That melds nicely with the noir aspects, where the world is hugely weighted against you unless you have stacked the deck yourself and solving a mystery doesn't necessarily mean justice is achieved.

Enter Isako, a woman in her fifties who has been working in corporate life for decades. Her job is something of a cross between a consigliere and a bodyguard; she helps plan her boss's corporate strategy and she also defends his life. Isako understands she's a cog in a system; she has a role to play and she does it well, even if it means sometimes doing terrible things. Her life is dedicated to serving her Principal, and that means following their orders. But now, faced with the end of her career, Isako is also facing that big existential question: in the grand scheme of things, what did her work and her life mean? What legacy will she leave behind?

I understand some of the misgivings of people looking for the next GREEN BONE SAGA. I've seen a few comments that people missed having a sprawling cast of complex characters. But bear in mind this isn't a grand sweeping trilogy with 1500 pages at its disposal. This is a standalone (if still a hefty one) that is getting through a complex story. There's only time to build out a few characters with true depth. You'll get to know a few people really well, and some you'll only see the surface of, but that doesn't detract from the overall story.

I will admit, there were times when I wasn't sure how I was going to ultimately feel about this book. It is broken into three parts, and after spending the first half of the book getting to know and root for Isako, it's jarring to switch to following a different character. But after Isako uncovers the what of the mystery, this new character perspective offers the WHY of the mystery, and that's the thread that ties everything together. It's what makes the finale really land when the last chunk of the book switches to resolving the conspiracy that's been exposed.

As a result, the ending is a quiet gut punch. Jade Legacy may have left me a bawling mess, but The Last Contract of Isako had me just staring into middle distance, unpacking everything that happened in the last 50 pages and what that meant for the characters. It's an ending that somehow manages to be both tragic and hopeful and not at all where I thought things would end when I started the journey.

The Last Contract of Isako is not here to fill you with sunshine and it's not quite here to stomp on your heart. Instead it leads you through a world that is completely unbalanced, slowly filling you with existential dread. Surely society can't be this uneven, surely there's a way out. Surely a life will have meaning when all is said and done. But if you're looking for those reassurances, The Last Contract of Isako is not here to offer them.
