Tessa Treslow never wanted a small town life. As soon as she graduated high school, she happily escaped her tiny town to join the U.S. Army, leaving New Oslo, Idaho, population 852, firmly behind her. Twenty years later, the hometown hero is finally ready to come back—even if she has just a visit with loved ones in mind while her family is hoping to convince her to stay for good. With her fawn boxer dog, Vince, in tow, Tessa falls into the unsettlingly familiar small town life, helping out in her family's general store and her feisty Aunt Edna's auto body shop. But her peaceful homecoming is suddenly shattered when the dead body of a crooked con man turns up in her aunt's shop, and the police have some serious questions for the family. To make matters worse, the sheriff in charge just happens to be Tessa's ex-boyfriend... and things did not end well between them all those years ago. When it comes out that the con man was trying to get his hands on the family business, Tessa knows they're in trouble. With her family in danger of being dragged away in handcuffs, Tessa becomes a woman on a mission to find the con man's killer. Between a slew of suspects, a meandering moose, and a handsome newcomer with his eye on Tessa, she has her work cut out for her. But when the killer changes tactics—putting everything her family holds dear in jeopardy—Tessa begins to realize what home really means to her. Can she be the hero for her hometown once again... before it's too late?

Retired US Army officer Tessa Treslow has settled in with her Aunt Edna in her hometown of New Oslo, Idaho. After the disasters of the previous fall, Tessa and her family are back on their feet as they start a new dream venture: a vehicle restoration business, "BOSS—Band of Sisters Services, call the She-canics." Tessa and the enticing local math teacher, Nick Hunt, are also working together to organize a charity run during the New Oslo Pioneer Days festival. All seems to be going well... until Tessa finds a dead body in the town park! The murder victim is a stranger to their small town, who claimed that she was the illegitimate cousin of Tessa's best friend, Deputy Petunia "Freddie" Frederickson. The victim's bloody finger is pointing to a mark on the veterans' honor roll sign, circling the names of Freddie and her grandfather. Complicating matters, Freddie was witnessed in an altercation with the woman just before her death, and it was Freddie's knife found at the scene. In order to help her best friend, Tessa and Aunt Edna search for the real identity of the victim. Was she actually a long-lost family member? Who would want her dead? And what was she doing in New Oslo? Tessa is determined to find out... even if the answers lead her straight into the crosshairs of a killer!
