A family vanishes without a trace. One mother will cross worlds to bring them back. Marda is the warden of the Stellar Bridge, a space portal that connects her planet to Earth. Six years ago, she watched her family enter the portal, never to emerge. It was supposed to be safe. But something went wrong. Now that portal is acting up again, and it's pulling others from Earth into its reach. Ben, a stockbroker lost in numbers and blind to the people closest to him. Lily, a college graduate who can’t escape her parents' house, and is yelled at by someone—everyone—every single day. Tony, a young man who gave up everything to care for his dying mother. Now that she's gone, he doesn't know who he is. Their paths collide in the BETWEEN—a place where time twists and nothing is stable, and survival isn't guaranteed. \— From USA TODAY bestselling author Maureen A. Miller comes this character-driven sci-fi mystery about family, survival, and how far we'll go for love.
