Legal thrillers that put the system on trial.
Derek Fermin writes grounded, high-stakes legal thrillers built on conspiracies that are fictional but feel entirely plausible. His books focus on the pressure, politics, and courtroom maneuvers that appear when the rules stop protecting the people they were meant to serve.
A single sealed case. A nationwide conspiracy.
Case by case, David Mercer learns that the system he swore to serve was engineered to protect power, not people. Follow the trail from one suspicious client to the shadow network running beneath the courts.
Other courts. Different verdicts. Same stakes.
Step into new courtrooms with judges, jurors, and attorneys who are one bad ruling away from losing everything. Each book stands alone—you can start with whichever case calls to you.
The Liberty Docket
A federal judge receives a desperate letter from a death-row inmate that cracks open a forgotten case— and suggests the real conspiracy has been hiding in his own courthouse all along.
The Juror’s Lie
Twelve jurors. One hidden agenda. And a woman willing to burn a trial to the ground to expose the truth about her sister’s murder.
