Zarya's right hand is a mysterious man known only as Kere. But Kere has a dark secret. Born into a world that is as privileged as it is corrupt, his real name is Darling Cruel—and he is heir to the government Zarya wants to overthrow. Like Zarya, he wants his uncle, who murdered his father and stole his crown, to pay for his crimes. His loyalties divided, Darling has lived life torn between the two roles. No one has ever seen the real him. No one except Zarya. She's the only person he's ever fully trusted. But when she allows a weapon he designed for her to be used against his beloved sister, all bets are off. The hero is now the monster. Betrayed by the Resistance, Darling's goal is not only to reign, but to kill every Resistance member he can find. Zarya is the only one capable of stopping Darling's reign of terror. But can she reach past his insanity to restore the hero who once fought by her side?
