For Jessica Turner, the stars have always been her escape. Orphaned young and burdened with a lifelong battle against Type 1 diabetes, she's spent most of her life keeping people at arm's length. Her job at a deep-space research facility in Maryland suits her perfectly: just her, the data, and the quiet hum of machines tracking the endless dark of space. But when impossible readings start pouring in, objects entering the solar system that shouldn't exist, Jessica's carefully ordered world shatters. Moments later, the world itself follows. An extraterrestrial invasion strikes without warning, leaving cities in ruins and governments in chaos. Forced to flee for her life, Jessica's survival depends not only on her dwindling insulin supply but on her will to keep going in a world that's falling apart. Then, against all odds, she saves another survivor, a tough, sharp-witted bartender named Sadie Marie, whose fiery spirit clashes with Jessica's quiet logic. Together, the two women embark on a desperate journey toward a rumored government bunker that may hold the key to humanity's survival, and the medicine Jessica needs to stay alive. As danger closes in from all sides, their uneasy alliance transforms into something deeper. In the wreckage of the world, Jessica finds something she never thought she'd have again: connection, trust... and love. But time is running out, for both of them. Jessica's condition grows more precarious with each passing day, and their path to safety is littered with both human and alien threats. To save herself, Sadie, and what's left of Earth, Jessica must risk everything-including her heart. When galaxies collide, will love be enough to light the way through the dark?
