Where to Start: The Recommended Reading Path
When diving into D.V. Berkom's action-packed thriller series, readers are often faced with a choice: follow the order in which the books were published, or follow the narrative timeline. Author D.V. Berkom officially recommends reading the series in chronological order. While Serial Date was the first book published in 2012, starting with the 2016 prequel novel, A Killing Truth, provides crucial backstory on Leine Basso's career as a professional assassin before she transitioned into anti-trafficking work.
For the absolute complete experience, hardcore fans should track down the prequel novella, Making Leine. This short story focuses on a sixteen-year-old Leine immediately after she is orphaned, tracing her transformation from a vulnerable, angry teenager into the deadly operative known as "The Leopard."
Chronological Reading Order
Following the author's preferred timeline, here is the chronological reading order for the Leine Basso thriller series:

Understanding the Chronological Caveats
While the chronological order is highly recommended for character development, reading in publication order is also a perfectly valid choice. If you begin with Serial Date, you will meet Leine as a retired assassin who is already haunted by her past. Starting this way allows you to uncover her secrets gradually, with A Killing Truth serving as an extended flashback that explains how she became so hardened. Either way, the emotional core of the series remains intact: Leine's journey from a cold-blooded killer to a champion of the exploited.
The Salome Trilogy-Within-a-Series
While most books in the Leine Basso series function as standalones, books 6, 7, and 8 (The Last Deception, Dark Return, and Absolution) form a distinct trilogy-within-a-series. This story arc focuses on Leine's intense rivalry with Salome, a cunning and deadly French-born terrorist. The conflict escalates from geopolitical espionage in the Middle East to a deeply personal vendetta, culminating in Leine going completely off the grid to protect her loved ones. For the best reading experience, these three books should be read back-to-back without interruption.
Practical Reader Advice
If you prefer to sample the series before committing, Bad Traffick is widely considered the best standalone entry point. It introduces Leine's work with the anti-human trafficking non-profit SHEN (Stop Human Enslavement Now) and features a tight, suspenseful plot that showcases her skills and moral compass. The series is known for its gritty, real-world themes, global settings ranging from Mexico to Tanzania, and a touch of romance through Leine's relationship with LAPD detective Santiago Jensen. However, the action is always front and center, drawing comparisons to Lee Child's Jack Reacher books but with a fierce female lead.
