After dying in the real world, Melanie Cruz awakens inside her favorite romantic fantasy novel as Catherine Zwart, the beautiful imperial princess whose original fate is execution at the hands of the man who becomes dangerously obsessed with her. Catherine is remembered as the obedient “Doll Princess,” a figure controlled by her half-brother, Lucien Zwart. Determined to survive, Melanie must break Catherine’s scripted behavior, expose the conspiracy surrounding the imperial succession, and win the trust of Gabriel Verdin, the duke’s estranged son—the one man capable of protecting her, and the man who once despised the original Catherine.
