Laura "Lo" Blacklock, a travel journalist, is still reeling from a recent break-in when she's assigned to cover the maiden voyage of the luxury cruise ship Aurora Borealis. The opportunity seems like a fresh start, but Lo carries anxiety and trauma with her onto the ship. As she boards and meets the wealthy, secretive group of guests and staff, Lo is on edge and struggling to feel comfortable or safe aboard the tight, isolated environment of the ship.
On her first night, Lo is awakened by a loud noise and glimpses what seems to be a woman being thrown from the neighboring Cabin 10. She rushes to alert staff but is told that Cabin 10 was never occupied, and no one is missing aboard. Lo's insistence breeds suspicion—her own recent struggles with anxiety and alcohol undermine her credibility among the guests and crew. As she investigates, Lo’s sense of reality grows more uncertain, heightening the novel’s tension between perception and truth.
Lo’s persistent efforts to find the truth place her in increasing danger. She navigates conversations with enigmatic guests, each with hidden motives and secrets, while facing gaslighting and attempts by others to dismiss or intimidate her. The lonely confines of the ship amplify her paranoia, and she can trust no one, not even herself. Ware deliberately blurs the lines between reality and imagination, maintaining suspense as Lo’s grip on fact and fiction is repeatedly tested.
Gradually, Lo uncovers a web of deceit and connections between the other passengers and the mysterious woman she’s sure she saw. The plot races toward a climax as Lo is captured, forced to confront her deepest fears and decide whom to trust. Ultimately, her tenacity and the relationships she forges enable her to outwit her adversaries, leading to the dramatic unveiling of the truth behind the disappearance in Cabin 10.
The novel concludes with a return to safety and Lo’s reflection on the ordeal. The journey leaves her changed, underscoring how trauma, isolation, and mistrust shape our perceptions and relationships. Through Lo’s persistence and vulnerability, Ware illustrates the dangers of ignoring intuition and the courage it takes to pursue truth, even when reality itself is in question.
