Overview

Two brilliant minds. One impossible equation.

Gloria Johnson can calculate lunar trajectories in her sleep, but as a Black woman at NASA in 1969, she's stuck typing other people's equations. Then she gets paired with Dr. Katrina Ivanova—the mysterious Russian defector who challenges every equation she thought she'd mastered.

Katrina Ivanova fled the Soviet Union for scientific freedom, only to find herself trapped by American bureaucracy. Her mother is still in Moscow, and the security chief holding her visa hostage wants one thing: intel on Gloria's family and their civil rights activities.

Professional competition turns personal fast. Gloria introduces Katrina to Star Trek. Katrina makes Gloria traditional Russian tea. Soon, their rivalry becomes something much more dangerous: attraction.

Katrina looks at Gloria like the solution to the most beautiful equation in the universe. Gloria's breath catches every time she hears Katrina's husky, accented voice. They move around each other like two celestial bodies in orbit—and it's going to destroy them both. Their breakthrough mathematics will help Apollo 11 reach the moon. But first, they need to figure out if love can survive the ultimate betrayal.
