Jordie is awed by asteroids, perplexed by planets, and mesmerized by moons. She can't believe her luck when she finds a black hole taking up residence in her desk at school. Of course she's keeping it. But when the black hole starts snarfing everything in sight--including Neptune the dog--she realizes that black holes need wide open spaces, galaxies to graze, and stars to slurp. So she sets things right. Just not before she embarking on a wild, time- and space-bending mission to save her pup.
