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...

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.

Just hours after finding Andromeda and crossing paths with her mother, Sienna Nealon finds herself 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... moreJust hours after finding Andromeda and crossing paths with her mother, Sienna Nealon finds herself up against a bigger threat than ever before.
