When Jocelyn's grandmother calls her asking for help, she drops everything and heads back home to Harmony Creek, Colorado. Her grandmother runs a living history museum and homestead where volunteers wear period clothing from the early 1900s and demonstrate how to make soap and shear sheep. The place is in financial trouble, and it needs the revenue from the annual festival to survive. Jocelyn's grandmother has broken her leg, and Jocelyn takes over the organizing. There's just one thing that makes this a little awkward: Mack, who's divorced, and who's now the caretaker and blacksmith at the homestead. Jocelyn and Mack have their own shared history, which includes both stolen kisses and teenage rivalry. Even as the past and present collide, they have to save the museum. Matchmaking grannies, a meddling mutt, and a flood of fun festival activities might just be enough to overcome their differences and forge two broken hearts back together.
