By day she works as a government messenger, by night she escapes into vivid, lucid dreams, navigating a world called the Stream. When her long-dead mother appears in a dream, Ashlyn is thrown into a world where time bends and thoughts are weaponized. She joins The Corvi Signum, a secret society of dreamers who are fighting to protect the Stream. But their fight is against a powerful enemy who wants to control it, manipulate people’s thoughts, and seize control of London.

Join Ashlyn as she navigates a world of dreams and danger, where the only way to save her friends and fight for freedom is to change the past.
