Vivien Featherswallow has always followed the rules. She has no intention of getting involved in protests or dragon politics—she only wants to secure a summer internship studying dragon languages, stay out of trouble, and make sure her little sister never has to grow up in Third Class. All she has to do is free one dragon.

By midnight, she has ignited a civil war.

With her parents and cousin arrested and her sister missing, Viv is taken to Bletchley Park, where she must work as a codebreaker. Her success means freedom for her family—her failure means death.

As Viv delves into the mysteries of an ancient dragon language, she begins to uncover dangerous truths. The peace treaty that has kept their world in balance is built on corruption, and the work she is doing may not just unlock secrets—it may be the key to tearing everything apart.
