There's nothing Lili loves more than celebrating the Spring Lantern Festival with her family. But this will be the first time she attends the festivities without her beloved lăolao. Though it's one of Lili's favorite days of the year, she can't help but wish, as she drifts off to sleep, that Lăolao were still there to enjoy bowls of sweet rice balls and solve fun riddles with her. Then, that night, the first full moon of the new year invites Lili on an incredible journey. Lili will travel to the bottom of the sea to visit the Dragon King and past the misty clouds to see the Jade Emperor. But will she get to see the one person she wants to see most in the entire world before the night is over?
