About this book

Rebellion happens in the shadows. In the sequel to the New York Times bestseller A Language of Dragons, language is the greatest weapon in a war between humans and dragons—and one translator has the power to change the world. Perfect for teen fans of Fourth Wing and Babel. Who is Vivien Featherswallow? It’s the question on the lips of every human and dragon in Britannia, and even she doesn’t know the answer.

Continue reading

Is she the Swallow, the face of the rebellion against the corrupt government and invading Bulgarian dragons? Is she a brasstongue, a translator on the cusp of discovering a new dragon language? Or is she just Viv, the girl who lost the love of her life after playing spy? Viv isn’t sure, but she knows she has to fight back. Armed with a machine that allows her to listen to dragons’ thoughts, a diary with the clues of a never-before translated dragon tongue, and her own need to avenge her lost love, Viv seeks out the elusive Hebridean Wyverns. If she can find them and convince them to join the war, the rebellion might have a chance. Viv will soon realize that while translation is a weapon, it might not help her on her journey to victory—or to finding herself.
