One year after the death of Jason Todd, Katherine Kyle has vanished from Gotham's elite - abandoning Wayne Manor, her family, and the girl she once was. Now known only by whispers on the street as Vesper, she stalks the city's underbelly in search of one thing: Joker. Haunted by blood-soaked memories and armed with nothing but her whip, her instincts, and her rage, Katherine will stop at nothing to make him pay - even if it means crossing every line Bruce Wayne swore to uphold. But Gotham is shifting beneath her feet. A silent war is brewing. New enemies rise. Old ones evolve. And in the darkest alleys of Gotham, rumors swirl of a vigilante who walks like a ghost... one that looks an awful lot like Jason Todd. Is it hope? Or is it another cruel joke? The hunt begins again. And this time, it's personal.

Katherine Kyle, a fifteen-year-old student at Gotham High and the secret daughter of Selina Kyle and Bruce Wayne, walks the line between two worlds: by day, a quiet student partnered with the notorious Jason Todd; by night, the elusive vigilante known only as Catgirl. Unaware of each other's identities, Katherine and Jason forge a bond in the classroom and on the streets of Gotham as Robin and Catgirl-driven by mutual curiosity and instinctive trust. When Bruce Wayne begins to suspect the truth about the masked girl haunting Gotham's rooftops, his carefully controlled world begins to fracture. As secrets unravel, old love is reignited, and a new team forms in the face of rising danger. But not all stories have time to heal. When trust is shattered and loss strikes, Katherine must choose: follow her father's code-or forge her own. A coming-of-age tale of identity, legacy, and the thin line between hero and vigilante.
