Sienna Nealon was a 17 year-old girl who had been held prisoner in her own house by her mother for twelve years. Then one day her mother vanished, and Sienna woke up to find two strange men in her home. On the run, unsure of who to turn to and discovering she possesses mysterious powers, Sienna finds herself pursued by a shadowy agency known as the Directorate and hunted by a vicious, bloodthirsty psychopath named Wolfe, each of which is determined to capture her for their own purposes…

Just hours after finding Andromeda and crossing paths with her mother, Sienna Nealon finds herself back at the Directorate and up against a bigger threat than ever before. Omega, the organization that unleashed Wolfe and others upon her, has declared war on the Directorate and the first strikes have already landed. Facing the seemingly unstoppable forces of Omega and Sienna's own mother, the Directorate seems poised for defeat when a new threat rears its ugly head - a traitor in their midst, one that may mean the destruction of everything Sienna has come to care about

Omega - a shadowy organization that is synonymous with power in the metahuman world. They have hunted Sienna Nealon since the day she first left her house, have killed countless Directorate agents and operatives, and now they unveil their greatest plot - Operation Stanchion, a mysterious phrase let slip by an Omega operative in the midst of a battle. Now Sienna must track the pieces Omega has in motion to confront her enemy before they can land their final stroke - and bring an end to the Directorate forever

After six months of intense training with the Directorate, Sienna Nealon finds herself on her first assignment - tracking a dangerous meta across the upper midwest. With Scott Byerly and Kat Forrest at her side, she'll face new enemies and receive help from unlikely allies as she stumbles across the truth behind the shadowy organization known only as Omega

Still haunted by her last encounter with Wolfe and searching for her mother, Sienna Nealon must put aside her personal struggles when a new threat emerges - Aleksandr Gavrikov, a metahuman so powerful, he could destroy entire cities - and he's focused on bringing the Directorate to its knees
