Because her mom is always on the move, Steph hasn’t lived anyplace longer than six months. Her only constant is an online community called CatNet—a social media site where users upload cat pictures—a place she knows she is welcome. What Steph doesn’t know is that the admin of the site, CheshireCat, is a sentient A.I.

When a threat from Steph’s past catches up to her and ChesireCat’s existence is discovered by outsiders, it’s up to Steph and her friends, both online and IRL, to save her.
