Where to Start Your Paranormal Journey

If you are new to the eerie, romance-infused worlds of Heather Graham, the best place to begin is at the very beginning with Haunted (2003). This book introduces you to Matt Stone, a skeptical Virginia sheriff, and Darcy Tremayne, a gifted psychic investigator. Together, they establish the essential dynamic of the series: a clash between hard-nosed skepticism and the undeniable reality of the supernatural.

Starting here also introduces you to Adam Harrison, the enigmatic founder of the Harrison Investigation agency. While each book features a self-contained mystery and a new romantic pairing, Adam Harrison serves as the recurring anchor for the entire series. Reading the books in order allows you to watch the agency grow from a tentative experimental group into a highly cohesive team of paranormal experts.

Chronological vs. Publication Order

Fortunately, Heather Graham wrote the Harrison Investigation series in chronological order. The events of each novel take place roughly in the year they were published, and the recurring characters age and progress in real time. Because the timeline does not jump backward or loop around, you do not need to worry about complex timeline variations. Just stick to the publication order listed above to enjoy the optimal narrative flow.

The Transition to the "Krewe of Hunters" Universe

For readers who fall in love with the Harrison Investigation team, the adventure does not end with The Killing Edge. This series serves as the direct precursor to Graham's massive, long-running Krewe of Hunters series, which began in 2011 with the novel Phantom Evil.

Within the lore, Adam Harrison leverages the success of his private agency to help the FBI establish a specialized, government-sanctioned unit of psychic agents known as the Krewe of Hunters. While the Krewe features a new cast of characters, the spiritual DNA, the rules of the supernatural world, and the influence of Adam Harrison carry over directly. Starting with Harrison Investigation gives you the complete backstory of how this supernatural universe was built.

What to Know Before You Start

To get the most out of your reading experience, keep these helpful tips in mind:

  • Stand-alone Mysteries: Every book has a complete resolution. If you cannot find a copy of a specific book, you can skip it and move to the next without losing track of the main plots.
  • Historical Roots: Heather Graham meticulously researches the history of her settings. Whether it is colonial Virginia, post-Katrina New Orleans, or New York's historic architecture, the settings play an active role in the ghost stories.
  • Vibrant Romance: In addition to the mystery, each book is a romance novel featuring a new couple. Expect a high degree of romantic tension alongside the paranormal action.
