"Raffi works in an observational cosmology lab, searching for dark matter. Every chance they get, they escape to see Britt, a queer sculptor who fascinates them for reasons they can't understand. As Raffi's carefully constructed life begins to collapse, they dream of a universe where they mean as much to Britt as Britt does to them. Touring parallel worlds, Raffi reaches for a life that feels authentically their own. But Raffi's divergent existences all lead back to the summer of Britt: the terrible thing Raffi did and the guilt that continues to chase them across realities." -- Publisher.
