Espionage and seduction—not skills Ilya honed to lead her people, but ones she'll need to free them. Held hostage by the emperor’s captain, Lucien, Ilya employs her wits and wiles to source information for a growing rebel movement. But Lucien isn’t the monster his fearsome helm depicts, and as Ilya unearths the truth about his beloved father-figure, the emperor, Lucien struggles with a reality more terrifying than the magical illusions he weaves. Each will have to determine where their hearts and loyalties lie—if the emperor doesn’t kill them first. A PROMISE OF FIRE meets THE BRIDGE KINGDOM.
