On a snowy Lunar New Year's Eve in Northeastern China, it's Dandan's last night with Yueyue. Tomorrow, she moves to America. The two best friends have a favorite wintertime tradition: crafting paper-cut snowflakes, freezing them outside, and hanging them as ornaments. As they say goodbye, Yueyue presses red paper and a spool of thread into Dandan's hands so that she can carry on their tradition. But in her new home, Dandan has no one to enjoy the gift with--until a friend comes along.

Millie loves to help LaoLao cook, especially her favorite dish. Dumplings! They gather fresh ingredients from Chinatown. Chives from Auntie Lim, shrimp from Uncle Lee, and juicy, fragrant lychees that make their days together so sweet. As the seasons change, LaoLao feels more and more tired, too tired to make dumplings. But can Millie make them without LaoLao? And will her dumplings come out delicious, and make LaoLao happy, too?
