Lexi Frye appears to be doing fine. She keeps her job, keeps her smile, keeps her routine. But something in her is dimming, and the cost of pretending is quietly mounting.
On a solo hike, Lexi slips through a crevasse and crashes into an unfamiliar underground cave system. For days she survives in darkness, clinging to memories and fueled by hope. But injured and weakening, beset by intrusive thoughts and resurfacing wounds, that hope begins to erode. Then, deep underground, she finds something that changes her forever.
When Lexi emerges into the light, she thinks her ordeal is over.
But the cave follows her home.
The darkness lingers, seeping into her days, loosening her hold on work, relationships, and even herself. Nightmares inflame her fear. Withdrawal becomes habit. She begins to vanish in plain sight.
Unexpected connection arrives in the form of a stranger intimately linked to her experience, and their tentative understanding grows into a surprising friendship. When a sudden, haunting reminder of those traumatic days shatters her fragile equilibrium, Lexi retreats further into herself. But her new friend, familiar with the pull of darkness and the shape of her pain, refuses to let her disappear.
