Harper Kane Books in Order

The Harper Kane trilogy centres on a woman who has already survived the worst the system can throw at her. After twelve years in prison, Harper walks out with a promise to keep, a son to reclaim and no illusions about how the world works.

In Trusted, teenage girls have been disappearing, and it barely makes the news. Before her release, Harper agrees to find out what happened to an inmate’s missing daughter. To have any chance of keeping that promise she needs a steady job and a safe place to live so she can regain custody of her own boy. What she actually finds is a human‑trafficking network that treats vulnerable girls as disposable. Harper is forced to use everything she learned inside—reading people, spotting danger, choosing when to fight—to keep her family safe, even if that means crossing lines she swore she would not cross.

Taboo picks up after those events. Desiree, newly widowed, is left with two lucrative clubs that her family are desperate to control. Instead of handing them over, she reaches out to Harper, pulling her into a fresh web of loyalties and lies. It has only been a year since Harper was tortured by Russian traffickers, and the scars are still close to the surface. When someone she trusted turns against her, Harper is pushed deeper into the Deacon family’s world and uncovers secrets that make her question who is really running the show.

By Torment, Harper is ready to take down Teddy Ryder and the network linked to a group known as The Click. Then she receives shattering news: her sister Charley, who has been working undercover in the trafficking world, is missing and presumed dead. Photographs of burned bodies and bloody handcuffs are offered as proof, but Harper refuses to accept it. She cannot rely on the police, so she follows the only path left—her own—to find the truth and, if possible, bring Charley home.

Throughout the trilogy, the focus stays on women who have been written off and the lengths they will go to for each other. The books confront trafficking, corruption and abuse head‑on, but always through Harper’s practical, no‑nonsense view of the world. Reading in order lets you see how her time inside shapes every decision she makes, and how the promise she made in a prison corridor echoes through all three stories.
