Book 1 The First Score
The case that changes everything begins with a bounty neither of them should take.
Sonnie Martinez and Rax Donovan are surveillance contractors three months into their partnership, running on synthetic protein and borrowed time. When Amunations owner Seka slides a data chip across the counter — Rachel Veicht, wanted alive, five thousand credits — they take the job. The logic is clean. The math is simple. What isn't simple: Rachel carries the same Kosov brand scar as Sonnie.
What begins as a bounty hunt becomes an investigation into the corporate infrastructure that made the Kosov trafficking network possible — and into the augmentation backdoors that Helix Industries has been quietly building into every piece of hardware it manufactures. The First Score introduces the city, the partnership, and the quiet architecture of something much larger that won't become visible for two more volumes.
The Kosov trial happens in this book. Eight hundred and forty-seven women freed. Fifteen executives convicted. And one warehouse collapse that changes everything that follows.
Book 2 Plasma and Lead
Six months after the win, someone inside Ghost's network is feeding Meridian Solutions everything they need.
Sonnie is running extraction operations in the eastern territories for Ghost's resistance network when three women die before she arrives. The extraction had been planned seventy-two hours earlier. Only five people knew the details. Someone talked — or someone has been listening for much longer than anyone knew.
Plasma and Lead is a mole investigation inside a resistance network that cannot afford to stop operating while it discovers who has compromised it. The suspect pool is built with care — Lee Santos arrives as the most probable answer and becomes something more complicated. The machinery of trust — how it is built, how it is tested, what it can survive — is the book's structural spine.
Rax returns in this book. Not through announcement. Through evidence. The anonymous operative who has been appearing at the moments that matter, military-grade augmentation and surgical precision and a tactical signature that Sonnie tracks and catalogues and refuses to name. Until a dog tag appears in her palm in the dark. The dog tag is the sentence the first two volumes work toward. The verdict at the end of the evidence.
Book 3 Blood Money
The architecture behind every case — the original layer, the one that owns everything above it — has a name: Helix.
Rax has been inside Ghost's network for two weeks when he finds it: a secondary communications layer, independent of everything the network had already mapped, running for five years minimum, coordinating something that doesn't go through normal corporate channels. Whoever built this is not reporting to someone. They are running it themselves.
Blood Money is the book where the bill comes due. Seven point three million people freed in seven minutes inside a maintenance shaft — the fulcrum the entire trilogy rests on. But the final tally is not the operation. The final tally is eight hundred and seventeen people freed across three years. Seventy-one lost. Those numbers do not balance. They are not supposed to.
Callum Stross gets a chapter. He is not confused about what he does. He has constructed a framework in which it is justified. That framework is not unusual. The series has been building toward his name since the first time Sonnie noticed the Helix logo on the wall of Amunations and filed it and kept moving.
What comes after Ghost is the book's quiet subject: the specific anxiety of carrying forward what someone built without being able to ask them whether you're carrying it right. Sonnie and Rachel answer that question not through reflection but through action. Which is the only way this series knows how to answer anything.
