On the day Tessa Quill is fired from the royal map office, a dragon calls the emergency line and demands a refund for a missing mountain.
Tessa should hang up. Instead, she follows the complaint to the northern border and finds a valley where the landscape has been erased one stone at a time. The only witness is a cursed knight who can speak nothing but the literal truth—and a dragon who insists the apocalypse is a customer-service error.
Soon Tessa is answering impossible calls: a moon that will not rise, a village trapped in yesterday, a sea asking for directions, and seven thousand ghosts waiting politely in a queue. Each ticket contains a fragment of a map that Tessa drew as a child, before anyone knew she could chart places that did not exist.
The hotline was built by the first dragon, who is now hiding beneath Tessa's office. If she closes the queue, the world loses its last warning system. If she keeps answering, the final caller will be the person she trusts most—reporting Tessa as the disaster.
