Laura Lam and Elizabeth May’s 2020 Seven Devils is the first book in their projected Seven Devils series.
Tholosians support their Empire because the Empire gives them no choice in the matter. The vast majority are programmed from birth to dedicate their lives to the Empire. The few who are not programmed are confined to slums. Despite this regimentation, the Empire has thus far failed to prevail in its five-century war against the Evoli.
There is a third faction in the conflict: the Resistance, who hope to overthrow the Empire and free its people.
