I jumped straight into Book 10 of the Sadie Gray FBI Mystery Series, The Shockwave Manifesto, and this one immediately felt bigger in scale than the previous books.
When a coordinated terror campaign erupts across Sacramento, targeting people, businesses, and infrastructure, Sadie Gray and Brad Tulle are pulled onto a joint terrorism task force trying to stop attacks that seem almost impossible to predict.
What makes the case especially terrifying is that there’s no clear suspect, no obvious motive, and no group claiming responsibility. Every attack feels calculated, strategic, and designed to spread fear across the entire city while the FBI races to figure out who is behind it before things spiral completely out of control.
But honestly, one of my favorite parts of this entire series continues to be Sadie and Brad. Their relationship feels so earned at this point. I love how Brad shows up for her when she’s at her absolute lowest, no matter what. He comforts her, protects her, and never makes her feel like she has to carry everything alone. And I love how openly Sadie admits she wants him — not just the relationship, but the life that comes with it.
What really got me in this book was seeing Brad finally seem ready for that, too. He’s moved away from the meaningless one-night stands and finally understands that Sadie wants something real: a family, commitment, permanence. She’s not just another passing relationship to him anymore, and you can absolutely feel that shift happening throughout this story.
But the case itself? Oh my goodness. This might be one of my favorite investigations in the series so far.
We first get introduced to the terrifying destruction caused by the New Murder Society when seven bombs explode simultaneously across downtown Sacramento. The chaos, fear, and sheer scale of the attacks immediately raise the stakes. And this one hit especially hard because Sadie was actually caught in one of the bombings herself.
She had been at a coffee shop with Roman when the blast happened. Roman didn’t survive, and Sadie barely did. She was thrown into the street by the explosion and hit by multiple cars, leaving her badly injured both physically and emotionally. That entire sequence was so intense and honestly heartbreaking to read.
And somehow, even after everything Sadie had already survived, the danger still wasn’t over. Later in the book, Brad and Sadie are violently rammed by a Bronco during another attack, leaving both of them injured. I swear this book never lets either of them breathe for more than five minutes before throwing them back into danger again.
But then the story twists in a direction I wasn’t expecting at all.
The man responsible for building the bombs wasn’t acting out of pure ideology. He was trying to uncover the names of the people who destroyed his life after his dishonorable military discharge — something that clearly left both emotional and physical scars. He took the fall while others walked away untouched, and discovering who those three people were became his obsession.
And once he learned the truth? Everything escalated.
The way he turned against the New Murder Society was shocking and kind of cinematic. He wiped them out in dramatic fashion, took down the head of that chapter, and finally got revenge on the three people he believed ruined his life before ultimately taking his own.
But what really lingers after finishing this book is the manifesto itself.
The politicians quickly move to bury it instead of letting the public see it, because exposing the corruption and power structures discussed inside it would threaten too many people at the top. The book leans heavily into the idea that powerful political figures, NGOs, and connected insiders protect each other in order to maintain control, influence, and money flowing through the same circles.
Whether you agree with all of it or not, it definitely gives the story an unsettling realism that makes it hard to stop thinking about after you finish reading.
The Shockwave Manifesto felt bigger, darker, and far more political than previous books in the series, but it still kept the emotional heart that makes these stories work so well. Between the nonstop tension, the layered investigation, and the continued growth between Sadie and Brad, I flew through this one and already can’t wait to start the next book.
