She went in as a fighter. She had no idea what they were really selling.

When UNR psychology student Sarah Martinez disappears after sending a cryptic final text about "the fights," Detective Hector Ramirez recognizes a pattern he has seen before. Young women. Financial desperation. Sudden cash income. Then silence.

The trail leads to Reno's brutal underground fighting circuit, where desperate women battle for prize money while someone far more dangerous watches from the shadows.

To expose the operation, Ramirez needs a detective willing to go inside.

Detective Celia Mendonca knew Sarah Martinez. They studied together, shared coffee over psychology textbooks, talked about their futures.

Celia volunteers.

Under a cover identity, she enters a world of warehouse brawls, encrypted betting apps, and handlers who evaluate fighters the way buyers evaluate livestock. She takes real punches from real opponents. She wins.

And with every victory, she climbs closer to the truth about what really happened to Sarah Martinez.

A truth that puts Celia's life in immediate danger.

Fight Night is the ninth book in the Detective Hector Ramirez series.

If you enjoy the procedural authenticity of Michael Connelly, the undercover tension of Harlan Coben, and the moral complexity of Don Winslow, this series belongs on your shelf.
