Because her mother is always on the move, sixteen-year-old Steph hasn't lived anywhere longer than six months. Her only constant is an online community called CatNet-- a social-media site where users upload cat pictures-- a site whose admin is CheshireCat, a sentient AI who loves cat pictures. When a threat from Steph's past catches up to her and CheshireCat's existence is discovered, it's up to Steph and her friends-- both online and IRL-- to save them. A near-future thriller about online privacy and out-of-control technology, and the importance of making connections in an increasingly fragmented society.
