Who are you? What underlying beliefs create the nature of the reality you inhabit? Martha Mathewson, a professor of psychology, was sure she knew who she was and what she believed in. For years she belittled her soon to be ex-husband, a revered astrophysicist, over his passion for the quantum universe, and for little green men and the star civilizations they come from. But when Don Mathewson suddenly dies, when she finds out he was murdered, his files have been targeted, and she's in danger, life as she's known it becomes upended.
As Martha is inexorably drawn into Don's world, a world which includes shadowy covert operatives who break into her house, she's moved to Tucson, Arizona, met an alto saxophonist/ rock hound, her daughter has joined her, and a small metal ball discovered in Don’s old oak desk (a ball which emits a bluish halo in the dark, dances to jazz, and communicates telepathically) is talking to her, saying it needs her help.
When she’s asked the metal orb ‘who are you?’ It says: ‘We are you.’ When she’s asked, ‘where do you come from?’ It answers: ‘Your future.’ When she’s asked, ‘what did you come for?’ It explains: 'To help you.’
In this new confusing life, Martha is being forced to abandon old beliefs about the nature of reality while also trying to stay alive.
