Ambush of the Heart
by Mary Connealy
2026
A posse of U.S. marshals escorting a prisoner through Colorado is ambushed by the outlaw’s family, leaving marshals wounded and fugitives loose. Marshal Owen Riley leads survivor Delaney Bridger and her injured brother toward safety, discovering grit, faith, and love along the trail.
Series background & context
Rocky Mountain Marshals launches readers into a late–nineteenth century West where the badge carries both authority and a sizeable target. The series follows a loose team of U.S. marshals tasked with escorting dangerous prisoners and fragile witnesses through the high passes and raw boomtowns of Colorado and the surrounding territories.
In Ambush of the Heart, a prisoner transport goes violently wrong when a gang of outlaws attacks the marshals’ detail. In the chaos, one marshal is killed, others are wounded, and the prisoner escapes. Marshal Owen Riley finds himself responsible for both an injured fellow officer and civilian siblings Delaney and Boone Bridger, who had joined the party when their train plans fell apart.
Forced to detour to a remote ranch to recover, the battered group still has to reach Fort Russell before their enemies regroup. Delaney proves to be far more than a passenger; her shooting skills and stubborn grit make her an asset rather than a liability, and sparks begin to fly between her and Owen even as bullets whistle past.
Future books continue to spin stories out of this core group of marshals and the criminals hunting them. Each novel pairs a different lawman or lawwoman with someone pulled into their dangerous orbit—escaped convicts’ relatives, frontier business owners, or fellow officers—while the larger manhunt and questions about justice versus revenge keep simmering.
Readers who enjoy the law-enforcement side of Connealy’s Garrison’s Law but want a historical setting will find Rocky Mountain Marshals a satisfying bridge between her frontier homestead tales and her modern-day suspense.
