Having a pen pal is exciting
One September evening, Gregory ties an index card with his name and address on it to the string of a silver helium balloon and lets it go from his window, into the city sky. Three weeks later, an envelope arrives in the mail. A farmer named Pete has found his balloon! Gregory writes back, and the two become pen pals, exchanging mystery gifts with each letter. Finally, Pete sends a gift that Gregory can identify only by a trip to the antural history museum, and the object turns out to be something truly amazing. With illustrations by the author, The Silver Balloon is perfect for early chapter-book readers.
