Kylie Hatfield Books in Order

Kylie Hatfield’s world starts small: she’s the chatty office assistant at Starr Investigations, filing paperwork and answering phones while daydreaming about solving real cases. When a woman goes missing and Kylie impulsively promises the family she’ll help, the series kicks off with a classic “be careful what you wish for” moment. Proving she can do more than type and fetch coffee means stepping straight into the path of a killer.

Kylie’s not a cop, and Mary Stone leans into that difference. Instead of badges and warrants, Kylie relies on stubborn curiosity, a big heart, and a knack for talking to people who’d slam the door on anyone else. That combination pulls her into cases involving missing women, hidden double lives, and crimes that reach far beyond the small city she calls home. Every shortcut she takes has consequences, and part of the tension in the series comes from watching her learn where the lines are—and how often she’s willing to cross them.

She doesn’t work alone for long. Linc Coulter, an ex‑soldier and dog trainer, is the reluctant anchor to Kylie’s chaos. He’s supposed to tame her unruly Newfoundland, Vader, and keep her out of trouble, but instead he’s dragged into stakeouts, break‑ins, and rescues that test his patience and his own ideas about right and wrong. Their banter, slow‑burn chemistry, and very different styles give the books a lighter, more humorous edge than Stone’s darker FBI series, without ever losing the sense that the danger is real.

The animals matter too. Vader, along with Linc’s search‑and‑rescue dog Storm, aren’t just comic relief; they’re working partners. From tracking scents to forcing Kylie to slow down and notice what’s around her, the dogs ground the stories in everyday detail and keep the stakes personal. When a case threatens them—or the found family Kylie builds at Starr Investigations—it hits harder than any twist of plot.

Across the series, Kylie grows from well‑meaning amateur to capable investigator. Each book hands her a new puzzle, whether it’s a client whose story doesn’t quite add up, a disappearance tied to a much larger predator, or a secret someone will kill to protect. She still misjudges people, goes places she shouldn’t, and ignores good advice, but the arc bends toward competence and hard‑earned wisdom.

If you like mysteries that blend danger with heart, a dash of romance, and plenty of dog hair, the Kylie Hatfield books show a different, more personal corner of Mary Stone’s crime‑fiction universe.
