Book 17 in a series, and I jumped in cold. That was my first mistake. Maybe my second mistake was finishing it anyway.
Let me cut to the chase: Bombshell is a competent but frustratingly paint-by-numbers FBI thriller that splits its attention between two investigations and doesn't give either one the depth it deserves.
Two Cases, Half the Payoff
Coulter runs parallel storylines here — Griffin Hammersmith investigating his sister Delsey's near-death experience at a music school in Virginia, and Savich and Sherlock working the frozen-body-at-the-Lincoln-Memorial case back in D.C. The Lincoln Memorial murder is genuinely intriguing as a setup: grandson of a former Fed chairman found with every bone broken, left frozen at the feet of Honest Abe. That's a hell of an opening image. But the Virginia plot — Delsey found naked, unconscious, covered in someone else's blood after a college party — felt like it belonged in a different, less interesting book. A lot of that storyline devolves into campus drama with thin characters I couldn't keep straight.
The "preternatural instinct" thing with Hammersmith bothered me too. Look, I've worked with people who had genuinely sharp tactical intuition. It's real. But the way Coulter handles it — Griffin just sort of knows things at convenient moments — feels less like a well-drawn character trait and more like a cheat code. Good investigators don't have psychic flashes. They notice what other people miss because they've trained their eyes. That distinction matters.
At 11 hours, there's enough plot to keep you moving, but I caught myself zoning out during the Virginia chapters more than once. And I was driving I-35 through San Antonio at the time, which means the road was actually more interesting than the story. That's not a great sign.
The Dual Narrator Gamble
Here's where this audiobook gets divisive. Paul Costanzo handles male characters, Renee Raudman takes the female roles. In theory, this should be a slam dunk — gender-split narration eliminates that awkward thing where a male narrator tries to voice a woman and sounds like he's doing a bad impression of his aunt. And sometimes it works. The handoffs between narrators are clean, and you always know who's talking.
But — and this is a real "but" — there's a tonal mismatch between the two that kept pulling me out of the story. Costanzo plays things relatively straight, with a measured FBI-procedural vibe. Raudman's delivery runs hotter, more theatrical. It's like watching a scene where one actor thinks they're in a drama and the other thinks they're in a soap opera. Neither is bad on their own. Together, they create this weird push-pull that changes the energy of scenes depending on who's talking. Some listeners love this setup. I get it. But for me, it was like listening to two different audiobooks stitched together.
I should note Raudman has a stack of narrator awards, and Costanzo's got serious voice work credentials. The quality of the recording itself is fine — clean audio, no weird artifacts or volume jumps. The issue isn't skill. It's chemistry. Or the lack of it.
Series Baggage and the Cold-Start Problem
Multiple people have flagged this and they're right: jumping into Book 17 without reading The Cove or The Maze (Books 1 and 2) means you're missing context on Savich and Sherlock that Coulter clearly assumes you have. I didn't feel lost, exactly, but I felt like the guy who shows up to a unit mid-deployment — everyone knows each other, there are inside jokes you don't get, and the relationships have a history that's implied rather than shown. If you're already invested in these characters from previous books, you'll probably get more out of this than I did.
The author clearly did their homework on certain procedural elements — the FBI bureaucratic structure, the way investigations get split across field offices. But there are moments where characters make decisions no actual agent would make, and those pulled me right out. When your protagonist visits a crime scene and starts freelancing without coordination, that's not "preternatural instinct." That's getting your badge pulled.
Who's This For (And Who Should Run)
If you've been riding with the Savich and Sherlock series for years, you'll probably enjoy this. It's comfort food for Coulter fans — familiar characters, dual investigations, a pace that doesn't let you get too bored. Worth your time? Here's the debrief: for series devotees, sure. For newcomers or people who want their FBI thrillers tight and realistic, start somewhere else. Whistler is one I'd point to instead — the procedural bones are sharper and the characters earn their instincts rather than just having them handed over by the plot.
If you're picky about military or law enforcement accuracy — and you know I am — this one will test your patience in spots. Not enough to throw the book across the room (or in this case, yank out the aux cable), but enough to roll your eyes.
Ranger fell asleep during Chapter 4. Make of that what you will.
