Heart of the Wilderness Books in Order

Heart of the Wilderness is Sarah Morgenthaler’s contemporary romance series set against the snowy country and working-ranch life of northern Idaho. It begins with The Christmas You Found Me, a story that uses a holiday setting and a marriage-of-convenience premise to explore grief, family, money worries, and the slow return of hope.

The first book centers on Sienna Naples, whose family has cared for their Idaho land for generations. Her divorce has just become final, and Christmas feels especially lonely with her parents gone. Sienna knows the ranch and the surrounding wilderness inside out, but she is less certain about what she wants her life to look like next.

Then an ad meant as a joke gets a serious answer.

Guy Maple is a construction worker and single father from Montana. He is trying to get the financial security and health coverage his four-year-old daughter, Emma, needs while she waits for a kidney transplant. When Guy answers the ad for a husband for hire, he is not looking for romance. He is looking for a way to protect his child.

Sienna and Guy enter an impulsive marriage of convenience, and the story takes their practical arrangement seriously. They are strangers carrying very different kinds of pain, so trust does not arrive all at once. Emma is not simply a reason to put the adults together, either. Her illness shapes Guy’s choices and raises the emotional stakes for the whole new family taking shape.

The Idaho setting matters throughout. Sienna’s ranch and the nearby Frank Church Wilderness offer beauty, isolation, hard work, and space to think. The landscape supports the book’s quieter moments, but it also reflects how exposed the characters can feel when their plans fall apart. Snow, animals, ranch chores, and small-town connections keep the romance grounded in daily life.

This is a gentler-paced, more emotional branch of Morgenthaler’s work than the broad small-town comedy of Moose Springs. There is still warmth and some offbeat animal energy, but the main tension comes from whether Sienna and Guy can build something real while facing problems neither can solve alone. Start with The Christmas You Found Me for a holiday romance about chosen family, second chances, and making room for love when life is still complicated.
