Dante Mercer is a 25-year-old gamer, introvert, and professional homebody whose idea of a perfect Friday night involves video games, junk food, and absolutely zero human interaction.

That changes when he stumbles into a suspicious little shop and pays $50 for a beautiful gray cat imprisoned inside a shimmering cage.

What Dante doesn't know? His new feline companion is actually a shapeshifter capable of becoming a fully grown woman.

And she's perfectly content letting him believe she's an ordinary cat while she steals his food, monopolizes his bed, and quietly turns his peaceful little existence upside down.

One clueless gamer. One suspiciously intelligent cat. One very inconvenient secret.
