Description: Siblings Jiwon and Byeonggwan are on their way to their grandmother's house by subway. They've ridden the subway many times with adults, but this is the first time they're going alone. Big sister Jiwon worries about getting on the wrong train or missing their transfer station, while her carefree little brother Byeonggwan bounces around without a worry in the world. This picture book lovingly captures every step of their subway journey to Grandma's house. The illustrations, based on careful observation of real subway stations inside and out, add extra charm and realism to the story. From the stairs that must have seemed impossibly tall and steep to the two children, to the ticket booth, turnstiles, platform, and the inside of the subway car itself, the scenes are depicted so vividly that readers can compare them to the subways in their own neighborhoods. The subway is also full of all kinds of people: someone listening to music, someone reading a book, someone scrolling on their phone, someone sleeping with their mouth open, someone sneaking a peek at the newspaper the person next to them is reading, and even a blind beggar—a familiar sight on many real subways. But the story isn't just about what can be seen. When the two children doze off, they dream that the entire subway car has turned into a world full of puppies—the very puppies they had stopped to admire on their way to the station—appearing in droves and comforting the children's wish for a dog of their own. This book brings together the fun of everyday subway scenes and the delightful imagination of childhood, all captured beautifully in its illustrations.
