At the edge of the world, biologist Laurel Salter is hiding from everything she’s ever known. For 10 hours a day, six days per week, she works as a dishwasher at McMurdo Station, an isolated research base in Antarctica. She tells no one that before she arrived, she was a renowned young scientist with a promising career and a family. But even in this remote outpost, Laurel can’t escape her past. When a strange light appears across the ice --- and draws a group of physicists to McMurdo --- her former husband, Eli, won't be far behind. Laurel is captivated by the Arc: its surreal glow; the way it seems almost alive. And though Eli is reluctant to test her wildest theory, Laurel is convinced that the Arc leads down a rabbit hole and into a world they can barely imagine.
