Chicago, sometime. Two people meet in the armory of 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. After their meeting, those things do not change. Everything else, however, is slightly different. A glimpse into the nature of love, what it means to be unwell, and how to face the fractures of yourself and still love as if you're not broken. From the no.1 international bestselling author of 'The Atlas Six'.
