This gripping third installment of the Empress Irini Series is set in the cutthroat world of 8th-century Byzantium, where power, betrayal, and ambition collide in a deadly game for the throne.

When Constantine's father dies unexpectedly, the nine-year-old is thrust onto the imperial throne, with his mother, Irini, assuming the role of Regent. But as Irini consolidates power and ruthlessly blocks her son's attempts to rule, Abbess Thekla finds herself torn between loyalty to the ambitious empress and a growing allegiance to the rightful emperor, Constantine.

Irini forces Constantine into an unwanted marriage to the unpopular Maria, prevents him from gaining his full authority at eighteen, and has him imprisoned when he dares to challenge her dominance. But Constantine's loyal army rallies to his side, freeing him and overthrowing Irini's reign. Now, the battle for the throne intensifies as a resourceful and relentless Irini vows to stop at nothing to reclaim her power.

Thekla must navigate a dangerous web of deception and intrigue-can she prevent the mother and son from destroying each other, or will Irini's savage ambition tear the empire apart?
