Trinity Investigative Team Books in Order

The Trinity Investigative Team follows a group of private investigators and former military professionals who take on cases where the official answers are missing, the danger is immediate, and the people involved have few safe places left to turn.

Every case is personal.

The series begins with Taken at Christmas, when former deputy Mia Galloway and her adopted daughter become targets after a Christmas-parade attack. Investigator Hayden McGrath, Mia's late husband's best friend, steps in to protect them when the child's birth mother is found murdered. That mix of family history, grief, and an urgent investigation sets the tone for the books that follow.

In Protecting the Orphan, private investigator Rebecca Campbell and retired soldier Heath Adler must keep Rebecca's infant nephew safe after her stepsister is murdered. Buried Mountain Justice sends private investigator Kelsie McIlheney back to her hometown, where she witnesses a killer burying a victim and must work with Special Agent Noah Cross, the man she left years before. Retribution in the Mountains centers on former Army investigator Melanie Shaw, whose witness-protection cover is destroyed by a bomb.

The ongoing link is the Trinity team itself. Its members are trained, resourceful, and willing to lean on one another, but each book gives a different pair a case shaped by their own past. Former partners, old loves, family ties, and professional loyalties all become complications when a killer is closing in.

The settings often bring the action into mountain communities and rural spaces, where distance, weather, and isolation can make a bad situation worse. The cases involve murder, abduction, witness protection, buried secrets, and long-running vendettas, so the suspense is brisk without losing sight of the characters.

These are romantic suspense novels with a team focus. Readers can enjoy an individual mystery on its own, but reading in order adds more weight to the friendships, shared history, and hard-won trust inside Trinity Investigative Team.
