In the Dinosaur's Paw

Luckily Richard finds a ruler in his desk–with a dinosaur’s initials–and he’s sure the ruler is special. And then he finds out it has magic powers.All his wishes begin to come true: Snow stars falling, he remembers to do his homework, and the bully Drake Evans gets sick. But now with Drake sick in bed, Richard begins to worry. His only hope is the magic ruler–but it’s gone.What will help him?
