Octavia has only ever had one goal: to follow in the footsteps of her parents and become a prestigious whitecoat, one of the scientists who study the natural wonders of Faloiv. The secrets of the jungle’s exotic plants and animals are protected fiercely in the labs by the Council of N’Terra, so when the rules suddenly change, allowing students inside, Octavia should be overjoyed. But something isn’t right. The newly elected leader of the Council has some extremist views about the way he believes N’Terra should be run, and he’s influencing others to follow him. When Octavia witnesses one of the Faloii—the indigenous people of Faloiv—attacked in front of her in the dark of night, she knows the Council is hiding something. They are living in separate worlds on a shared planet, and their fragile peace may soon turn into an all-out war. With the help of Rondo, a quiet boy in class with a skill for hacking, and her inquisitive best friend, Alma, Octavia is set on a collision course to discover the secrets behind the history she’s been taught, the science she’s lived by, and the truth about her family.

In the forty years since the Vagantur landed on Faloiv, the planet has existed in a tenuous peace between the humans who live in the enclosed community of N’Terra and the Faloii, the indigenous population. But after uncovering the shadowy secrets of the Council’s newly elected leader and helping a kidnapped Faloii man escape, sixteen-year-old Octavia knows that conflict is looming. Her discovery of a separate population of humans—including her grandparents—only serves to show her how out of touch humans are with reality on Faloiv. Then the Faloii discover the N’Terran’s latest experiment: an artificially weaponized creature, and Octavia realizes that it’s up to her to prevent her people from causing any further destruction. More determined than ever, Octavia and her friends set out to understand the scope of humanity’s history. However, nothing can prepare them for the full weight of what they discover about both their home on Faloiv and the Origin planet. And as she learns to control her ability to communicate through the Artery, the network that connects everything on Faloiv, Octavia must act to change her people’s future before the natural balance on the planet shifts forever.
