Guardian (Natasha Deen) Books in Order

At the center of the Guardian trilogy is Maggie Johnson, a teen in Dead Falls, Alberta, who can transition the dead from one side to the next. That job is strange enough on its own. Trying to survive high school while doing it makes life even messier. From the start, the books balance two pressures at once, the everyday grind of being a teenager and the very real danger that comes from being close to the dead.

The first book, Guardian, kicks off when Maggie finds the body of Serge Popov, the town bully, and winds up with his trapped spirit in her room. She would love to ignore him. She cannot. If Serge does not cross over, Maggie becomes a target herself, and that turns a personal nuisance into a murder investigation. From there, the series settles into its pattern, each book brings a new death, new clues, and a deeper look at the rules and costs of Maggie's gift.

Dead Falls matters. It is not just a backdrop with a spooky name. The small-town setting makes everything tighter, from rumors and grudges to family history and public distrust. When people start to fear Maggie, there is nowhere for her to disappear to. The world of the living sits right beside the world of the dead, and Natasha Deen keeps that overlap practical and eerie at the same time. Ghosts are part mystery, part burden, and sometimes the only witnesses Maggie can trust.

Serge becomes one of the series' anchors.

What starts as hostility slowly turns into a sharper, funnier partnership. By Gatekeeper and Game's End, Maggie and Serge are dealing with more than one ghost at a time. New deaths pull them into fresh cases, while Maggie's powers grow harder to control and more dangerous to ignore. The tension keeps widening, from one murder to a town that no longer feels safe, then to supernatural threats with direct ties to Maggie and her family.

These books read like paranormal whodunits first, but they also work as coming-of-age stories. Maggie is not just learning how to solve crimes. She is learning what responsibility feels like when no adult can fully share the weight, how fear can twist a community, and how compassion sometimes looks a lot like stubbornness. There is romance around the edges, but the main engine is mystery, loyalty, and the question of what the dead still owe the living.

If you like ghost stories with rules, small-town secrets, and a heroine who would probably prefer a quieter life but never gets one, this series is easy to settle into. Start with Guardian and keep going in order. The cases build on each other, and so does Maggie.
