S.F. Williamson Books in Order

In an alternate 1923 London, Vivien Featherswallow's actions shatter the peace between humans and dragons. Recruited to decode a secret dragon language at Bletchley Park, she must decide whom to trust while her family's survival depends on her work.

Wanted by the government and made a symbol of rebellion, Vivien Featherswallow struggles to help from hiding. Her search for an elusive dragon species takes her to remote Scottish islands, where a new language may offer a way to end the war.

With London under dragon occupation and rival factions dividing both species, Vivien rejoins her fellow rebels. Drawn toward the enemy's court, she must navigate shifting alliances and painful sacrifices while searching for a peace that weapons alone cannot secure.
