Twenty-one-year-old Wren Harper thought she was safely hidden in her cave. After all, They seemed more interested in places like San Francisco than a small town like Cave Junction, Oregon. It had been twelve months since the powerful fae invaded, and in that time, Wren couldn't help but notice the creatures had begun purifying the world: air was cleaner, the rivers clearer, nature was healing. Ambushed at her childhood home as Wren struggles with her innate desire to survive or to join her parents in death, she cowers, waiting for the killing blow. Only to be spared by one of Them. Shadowed by doubt, Wren must confront a possibility she fights to reconsider: what if some humans want the fae in control? And what if it's the right thing to do: for the planet, and for humanity?
