Cleo and the Cats by Jamieson Wolf
Shortly before Christmas, Cleo is visited by a cat; it watches her as she sleeps from her bedroom window.
Cleo has the strange sense that the cat is watching her; more that it understands her when she speaks.
Soon, there is not one cat watching her but three.
To learn the secret of the cats, Cleo will have to learn there is still magic in the world.
