The Magic Tree House books are great, Jack and Annie's adventures never seem to end. But if you want to mix it up with a new brother sister globe trotting duo try Recipe for Adventure! It is a new series of chapter books by Giada De Laurentiis. In the first book the siblings travel to Italy then France in the 2nd and on to China.
