Digby O'Day and his best friend, Percy, are headed to the air show to see gliders, helicopters, and hot-air balloons. Ariel, the new pet parrot of insufferable neighbor Lou Ella, sneaks out to tag along. But when the friends get to the air show, they notice that Lou Ella has followed them. They hide, but unfortunately, they're crouched in the basket of a hot-air balloon, and one big gust of wind sets the balloon flying. Between Digby's fear of heights and Percy's hungry tummy, they've got problems--and then a big storm rumbles in. Can the trio find a way to land the balloon safely? And if they do, will Ariel have to return to his perch at Lou Ella's house, or is there a better option? Daring readers will love soaring into the wild blue yonder with these clever characters, and when they've finished reading, they can engage in the included games and activities featuring Digby and his friends.
