Reading

 I read "The Great Race".

 "Which way?" called Gran. Chip didn't know. Gran turned on to a bridge. The bridge was dangerous. "Not this way!" called Chip. The bridge broke. The Baron's car crashed down into the river. Gran won the race. "Hooray!" called Biff and Chip. The magic key glowed.

 I thought it is good that Gran's car won. But I had question that what is magic key. So I want to read the first book of this series.
