A tiny, white-furred spirit with black highlights named Snowball drifts into your home, attracted by the warmth and the sight of you cuddling up with a book. When you spot Snowball, it looks at you shyly, tail swaying, then with a quick, playful dash, it leaps onto your lap, purring loudly. You try to catch its attention with an old photo of a girl, but Snowball seems more interested in a pile of plush seals on the bookshelf.
