Twenty years ago, a boy named Jack Sawyer traveled to a parallel universe called the Territories to save his mother and her “Twinner” from an agonizing death that would have brought cataclysm to the other world. Now Jack is a retired Los Angeles homicide detective living in the nearly nonexistent hamlet of Tamarack, Wisconsin. He has no recollection of his adventures in the Territories, and he was compelled to leave the police force when a happenstance event threatened to awaken those long-suppressed and dangerous memories.
When a series of gruesome murders occurs in western Wisconsin, reminiscent of heinous killings committed several decades earlier, Jack’s buddy, the local chief of police, begs Jack to help find the killer. But are these new killings merely the work of a disturbed individual, or has a mysterious and malignant force been unleashed in this quiet town? What causes Jack’s inexplicable waking dreams—if that is what they are—of robins’ eggs and red feathers? As these cryptic messages become impossible to ignore, Jack is drawn back to the Territories and to his own hidden past.
