Paperback. CHICAGO, SOMETIME—

Two people meet in the Art Institute by chance. Prior to their encounter, he is a doctoral student who manages his destructive thoughts with compulsive calculations about time travel; she is a bipolar counterfeit artist, undergoing court-ordered psychotherapy. By the end of the story, these things will still be true. But this is not a story about endings.

For Regan, people are predictable and tedious, including and perhaps especially herself. She copes with the dreariness of existence by living impulsively, imagining a new, alternate timeline being created in the wake of every rash decision.

To Aldo, the world feels disturbingly chaotic. He gets through his days by erecting a wall of routine: a backbeat of rules and formulas that keep him going. Without them, the entire framework of his existence would collapse.

For Regan and Aldo, life has been a matter of resigning themselves to the blueprints of inevitability—until the two meet. Could six conversations with a stranger be the variable that shakes up the entire simulation?
