The Horse Syndicate

At Harper Haven Horse Sanctuary, Riley Harper has built a refuge for the broken, the discarded, and the dangerous miracles no one else will fight for. High fences. Endless vigilance. Horses worth killing for.

When a poisoned colt is found dying beside a deliberately cut fence, Riley knows this wasn’t vandalism—it was a message.

What begins as a targeted attack on her sanctuary quickly escalates into something far darker: an international syndicate trafficking elite horses, laundering fortunes through insurance fraud, doping scandals, and silent disappearances. These aren’t amateurs. They’re ghosts—bankrolled by billions, protected by power, and embedded at the highest levels of the sport.

As Riley assembles a covert team—an unflinching veterinarian, a ruthless hacker, a legal strategist willing to bend the rules, and an Interpol agent operating off the books—she discovers the truth is more terrifying than she imagined. The enemy isn’t lurking outside the gates.

They’re already inside.

With her horses marked, her sanctuary compromised, and the line between protector and predator erased, Riley makes a choice that changes everything: she won’t harden the target and hide.

She’ll hunt the ghosts.

Because if they came for her horses, they came for the wrong woman.

Gripping, cinematic, and razor-sharp, Riley III delivers elite-horse drama, international crime, and a relentless heroine who turns sanctuary into a battleground.
