A luxury train slices through the Arctic night—and Nova Wren is the only passenger who didn’t buy a ticket.
Broke, desperate, and chasing one last story, Nova boards The Frost Line expecting a miracle. Instead, she steps into a moving labyrinth built for power: velvet corridors, sealed cars, surveillance screens…and three billionaire men who run the train like it’s a ritual.
Vale Mercer is charm sharpened into a weapon. Killian Drake is control dressed as calm. Ronan Black is the storm that never warns before it hits. They claim Nova is chosen, not invited—selected for a game where the rules shift, the doors don’t always open, and the women before her didn’t make it to the end.
As the Frost Line races deeper into white silence, Nova realizes the real danger isn’t the cold outside—it’s what these men want inside her: surrender, loyalty…or something darker that feels uncomfortably like desire. To survive, she’ll have to crack the train’s secrets, outplay three predators who never lose, and decide whether she’s their final candidate…or their reckoning.
