A Language of Dragons

EVERY FIRE STARTS WITH A SINGLE SPARK.

Welcome to Bletchley Park… with dragons.

London, 1923. 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 an internship studying dragon languages, and make sure her little sister never has to risk growing up Third Class. By midnight, Viv has started a civil war.

With her parents arrested and her sister missing, all the safety Viv has worked for is collapsing around her. So when a lifeline is offered in the form of a mysterious ‘job’, she grabs it. Arriving at Bletchley Park, Viv discovers that she has been recruited as a codebreaker helping the war effort – if she succeeds, she and her family can all go home again. If she doesn’t, they’ll all die.

At first Viv believes that her challenge, of discovering the secrets of a hidden dragon language, is doable. But the more she learns, the more she realises that the bubble she’s grown up in isn’t as safe as she thought, and eventually Viv must decide: What war is she really fighting?

An epic, sweeping fantasy with an incredible Dark Academia setting, a clandestine, slow-burn enemies-to-lovers romance, and an unputdownable story, filled with twists and turns, betrayals and secret identities, A Language of Dragons is the unmissable debut of 2025, from an extraordinary new voice.

"A smart and original young adult riff on the dark academia aesthetic, SF Williamson’s book is a glorious mix of dragons, rebellion, language and romance, and the world-building is a joy." – Observer, best children’s books of 2025
