Cassie Quinn Books in Order

The Cassie Quinn series is a mystery thriller with a paranormal edge, the kind where the crime is real and the ghostly part raises the stakes instead of replacing them. Cassie isn’t a magician or a superhero. She’s a woman trying to hold down a normal life while the dead keep showing up with unfinished business.

Cassie works as a consultant to the FBI and other police departments, but her “insider” advantage is unusual: she can see and hear victims of murder. That ability is tied to trauma. Cassie survived a serial killer, and her connection to the dead has been both a weapon and a wound ever since. In the quieter stretches she tries to hide, even taking work in an art museum while keeping distance from her family.

For Cassie, death is never quiet.

Path of Bones opens with a fresh start that immediately goes off the rails when the ghost of a murdered woman appears in Cassie’s home. The message pulls Cassie into a case involving a killer who removes his victims’ hearts, and as she races to stop him she realizes she could be next. It’s a good blueprint for what the series does best: an urgent investigation, eerie clues, and a lead who can’t simply walk away from what she knows.

Later books keep building on that foundation. Cassie’s gift makes her valuable to investigators, but it also makes her vulnerable. She has to navigate skepticism, fear, and the very real danger that the person she’s hunting is watching her too. Each case brings its own puzzle, but Cassie’s personal arc keeps moving in the background, learning how to live with what happened to her, and figuring out whether her ability is a curse, a calling, or both.

The tone is tense and grounded. The supernatural element mostly shows up as communication, whispers, warnings, and the emotional weight of victims who want justice. The violence and the procedural work remain front and center, which keeps the books feeling like crime thrillers first, with the paranormal twist used to push the mystery into darker corners.

If you’re deciding where to start, begin with Path of Bones and continue in order through titles like Whisper of Bones, Symphony of Bones, and the later Shadow books, Etched in Shadow, Concealed in Shadow, and Betrayed in Shadow. The series rewards reading straight through because Cassie’s relationships, confidence, and control over her gift change over time.
