In Gotham City, childhood is a dangerous game - and nobody plays fair.
Melissa Kyle, the hidden daughter of Catwoman, spends her days slipping through shadows and her nights dodging the truth of who she is. Her best friend, Emily Nigma, lives for puzzles and mischief, while the other children of Gotham's rogues treat the streets like their private playground.
But when an underground "game" between the rogues' heirs turns into a real-world contest of theft, betrayal, and revenge, the line between play and crime begins to vanish. What started as a dare becomes a war between names - the Cats, the Clowns, the Crows, and the Riddles.
As alliances crumble and masks harden, Melissa finds herself standing on the edge between two worlds: the life her mother built in the shadows and the one a certain billionaire has no idea he left behind.
