Dragons soar through the skies and protests erupt on the streets, but Vivien Featherswallow isn’t worried. She’s going to follow the rules, get a summer internship studying dragon languages, be smart, be sweet, and make sure her little sister never, ever has to risk growing up Third Class. She just has to free one dragon.

By midnight, Viv has started a civil war.

With her parents and cousin arrested and her sister missing, Viv is brought to Bletchley Park as a codebreaker—if she succeeds, she and her family can all go home again. If she doesn’t, they’ll all die.

As Viv begins to discover the secrets of a hidden dragon language, she realizes that the fragile peace treaty that holds human and dragon societies together is corrupt, and the dangerous work Viv is doing could be the thread that unravels it.

S. F. Williamson is the author of A Language of Dragons and A War of Wyverns. She is fascinated by the way languages are born and was surrounded by them long before she undertook degrees in French and Italian. She has always known that languages are creatures that live and move and breathe, and as a child she learned that speaking them meant accessing ideas, traditions, and people she would only otherwise know from a distance. She is inspired by her work as a literary translator and the fact that no matter how intimately a linguist knows their languages, some meaning is almost always lost in translation. A graduate of Bath Spa University’s MA writing for young people program, Steph now lives in France with her husband and children.
