The Recommended Reading Order
For the best reading experience, it is highly recommended to read the DI Kelly Porter series in publication order, starting with the debut novel, Dark Game (2018). While a prequel novel, First Act, was released in 2026, it is best enjoyed after you have already become familiar with Kelly's character. Starting with the main series allows you to experience her return to Cumbria and watch her rebuild her life and career step-by-step.
As you progress through the series, the overarching character development, Kelly's personal relationships—especially with her family and colleagues—and the lingering effects of past cases evolve continuously. Reading out of order will spoil these long-term emotional payoffs.

Chronological Order: Where Does the Prequel Fit?
In early 2026, Rachel Lynch published a prequel novel titled First Act. This book changes the chronological order of the series if you prefer to read events in the order they occurred:
- First Act (Prequel, 2026) – Set in 2008 in London. It follows a 28-year-old Kelly Porter as she begins her dream job with the Metropolitan Police’s murder squad at Bethnal Green CID, long before her return to the Lake District.
- The main novels (from Dark Game through Cruel Truth and onward) follow chronologically from her return to Cumbria.
While reading chronologically is a fun option for a re-read, starting with the prequel is not necessary. Dark Game remains the definitive introduction to the tone, setting, and core dynamics of Kelly's world.
What to Know Before You Start
Rachel Lynch’s crime series is heavily defined by its regional authenticity. Having grown up in Cumbria, Lynch brings the Lake District to life, using real fells, lakes, and historical landmarks like Castlerigg as atmospheric backdrops. The landscapes are as much a character in the books as the detectives themselves.
Additionally, Lynch’s background in history and sports science gives the books a distinct edge. The police work is detailed and procedural, while her knowledge of human anatomy brings a gritty realism to the forensic aspects of the investigations. Readers should be prepared for dark themes, but they are always balanced by Kelly’s deep compassion and her struggle to manage a complicated family life, particularly her relationship with her sister, Nikki.
Rachel Lynch’s Wider Thriller Universe
If you finish the Kelly Porter books and want more of Rachel Lynch's writing, you can explore her other works. She has written another thriller series featuring Major Helen Scott of the Royal Military Police, which offers a slightly different, military-focused angle on crime solving. Lynch is also the author of several standalone psychological thrillers, including The Rift, The Rich, The Famous, and The Gathering (2026), which are perfect for quick, suspenseful reads between Kelly Porter novels.
