General Daynja Édo is a legend: head of the celebrated Boorhian Empire's military and possessor of a mask of untold power. She has raised her Shadow Army of seven assassins from childhood. But mounting disillusionment over a life of brutality, a petulant emperor, and prodding from The Artful Djinni force her to defy orders for the first time in her thirty year career. When the empire decides they no longer need Édo if they can get the mask, she must face the monsters of her own making and the legacy they've turned against her.
