Hounds and hares are like cats and mice. At least, that’s the way it is in Great Bone, a little village beside the river. Harley Hare and Hugo Hound see each other at school every day, and they’re interested in the same things. But they never talk to each other. Why? Because the Hare and Hound families can’t stand one another.

When the annual Big Race takes place on the meadow, Harley and Hugo find themselves racing neck to neck, until a terrible thunderstorm breaks out. Hugo is terrified of the storm and the lightning. Harley panics when they discover they are lost. It turns out that between them, they know just what to do. And, working together, they not only save themselves, but become heroes of the day as well.
