Sydney Rose Parnell

A young woman is found brutally murdered, and the main suspect is the victim's fiancé, a hideously scarred Iraq War vet known as the Burned Man. But railroad police Special Agent Sydney Rose Parnell, brought in by the Denver Major Crimes unit to help investigate, can't shake the feeling that larger forces are behind this apparent crime of passion. In the depths of an icy winter, Parnell and her K9 partner, Clyde - both haunted by their time in Iraq - descend into the world of a savage gang of rail riders.

It's been five months since Special Agent Sydney Parnell survived a violent confrontation with a gang of brutal thugs, an encounter that left her physically and emotionally scarred. Deep down, Sydney fears she isn't ready for another investigation. But when a woman is murdered on the train tracks and a child goes missing, she knows she's the only one who can lead the hunt for the killer. While Denver police and the FBI chase down blind alleys, Sydney focuses on a single cryptic clue left behind at the crime scene.

Railway cop and former Marine Sydney Parnell is on the hunt. So is a killer she knows only as the Alpha. They’re in a race to find Malik, an 11-year-old Iraqi boy with secrets to guard. Sydney wants to help him. The Alpha wants him dead. From the dark alleys of Mexico City to the mean streets of Denver, Sydney and her K9 partner, Clyde, use their wits and determination to chase down the ruthless killer. But when their path collides with his, Sydney realizes just how far-reaching and sinister the Alpha’s past is. And how far he’s willing to go to save his secrets.

Iraqi war vet and former railway cop Sydney Parnell is now the youngest homicide detective in Denver's Major Crimes Unit. In the past, gut instinct has served her and her K9 partner well. But it's not a trait Len Bandoni, her old nemesis turned reluctant mentor, admires. Not until Sydney's instincts lead to their first case: a man tortured and beaten to death, then left in a refrigerated train car with cryptic messages carved into his body.
