The Common Denominator (en Inglés) - Sean Donovan;Ken Kinsler

When a college professor challenges his students to question the invisible assumptions governing their lives, a small group begins to notice a terrifying pattern: those who truly understand his lesson tend not to survive it.

What starts as an academic exercise in free thought spirals into a decades-spanning investigation involving vanished scholars, forbidden questions, and a truth so destabilizing it appears to defend itself.

The Common Denominator is a slow-burn psychological thriller about control, inherited belief, and the perilous moment when a person stops outsourcing their thinking-revealing that the greatest danger may not be who controls the world, but what happens when you finally realize you are free.
