Derek is no ordinary dinosaur. He's little and green, and he lives in a house with Montmorency the mouse. Sometimes he wishes he could be more like Fang and Fearless, his frightening brothers, but mostly he is content just to do what he likes best - knit.

And then, slowly and strangely, something starts to happen in the wild outside . . .
