Liam Harper #3
Track Shift
Liam Harper came to Chicago to disappear. But trouble always finds him.
When ex-SRR operative Liam Harper rides into the city, he’s looking to stay hidden. His enemies are closing in—and one of them is Mason Carrick, the ruthless head of Aegis Security... who wants him gone.
But Chicago’s a city that doesn’t stay quiet. And when Harper intervenes in a violent beating near the South Yards, he discovers he’s stepped into something far bigger. Veronica Slate, the city’s most powerful real estate tycoon, is buying up land at any cost. And buried beneath her billion-dollar project lies a secret worth killing for—a toxic spill covered up decades ago by Aegis…and Harper’s own father.
Now Slate wants Harper silenced, and Carrick’s mercenaries are hunting him. But in Chicago, friends become enemies fast—and not everyone fighting beside Harper is on his side.
In a city built on secrets and steel, Harper must expose a conspiracy that could shatter Chicago—or walk away before it costs more lives, including his own.
Because in Liam Harper’s world, when the city pushes—Harper pushes back.

Track Shift by Jack Gatland is book 3 in the Liam Harper series. Liam is an ex-UK Special Forces member. He is in the US following clues as to why his father, Dominic Kane, was killed. Liam ends up in Chicago and gets involved in environmental poisoning. I love the way the author paints the scene drawing you into the story as he does so. This is fast-paced and exciting, a high octane read. It is very entertaining. There is a back story that runs through the books. Even though the books can be read by themselves, it would be better to start from book 1, Final Claim.
