The Recommended Reading Path
For the best experience, readers should follow the series in its official publication order. Because the characters share a tight-knit camaraderie and the overarching mystery of the team's handler, Rex, builds across each book, reading them sequentially provides the most satisfying narrative payoff. Each novel functions as a standalone romance with its own happily-ever-after, but the recurring background characters, evolving team dynamics, and structural subplots are best enjoyed from the beginning.
However, if you want the absolute complete backstory of the team, there is a hidden starting point. The Mountain Mercenaries are first introduced in Claiming Felicity, which is Book 4 of Susan Stoker’s Ace Security series. While not strictly necessary to enjoy the main series, this crossover novel acts as the unofficial prologue where the team makes their debut appearance.

What to Know Before You Start
Susan Stoker's novels are known for their alpha heroes, competent and resilient heroines, and fast-paced romantic suspense. However, readers should be aware that the Mountain Mercenaries series tackles heavy, real-world themes, including human trafficking, physical abuse, kidnapping, and complex trauma. Stoker handles these topics with sensitivity, focusing heavily on the healing process, mutual respect, and the strong bond of brotherhood shared by the ex-special forces operatives.
While the team operates out of Colorado Springs, their missions frequently take them across the globe, from San Francisco to Peru and the Dominican Republic. If you enjoy high-stakes adventure, tight-knit military families, and protective heroes, this series is an excellent fit.
