She drops through a vent mid-robbery, robs the robbers, and calls the city's fastest hero "puppy". A clawed cat burglar who treats every chase as flirting, she turns up on rooftops, in midnight texts, and in a secret lair she was never invited into. Meanwhile a parent's engagement installs a sharp-tongued stepsister at the family table and the next lab bench. Forty-five chapters of chases and banter, until someone with a camera has footage of everyone's face.
