The familiar flow of electricity was right beneath her fingertips. She could control it this time, couldn’t she?

Serena, be careful, Nora said.

She could jumpstart the engines. Her heart raced. She just had to touch the console. They were nearing the planet. Dangerously close. There were no other options. The shields were burning up. She reached out towards the controls.

Meet Natalie Brianne

Natalie spent her teen years commanding starships and navigating constellations—literally. Working at the Christa McAuliffe Space Center, she spent her formative years immersed in science fiction adventures, guiding live-mission crews through moral quandaries and galactic diplomacy. Later, as a planetarium navigator, she introduced people to the stars in real life—a job that inspired the very first scene of Keepers of the Zodiac.

A lifelong lover of mythology, stargazing, and stories with heart, Natalie blends science fantasy with emotional truth. Like her protagonist Serena, she knows what it’s like to feel like an outsider, to carry old wounds, and to long for a place to belong. Through the Zodiac series, she invites readers into a galaxy where wonder is real, courage is earned, and even the most unlikely heroes can change the stars.
