Make a wish. . . During the New Year's break, Plum and her friends travel to fancy, fashionable Nakhon City to stay with Sam and his mother, the powerful Lady Ubon. The New Year always brings food, parties, and the grand old tradition of making a wish.

At first, Plum is dazzled by the big city. But under the glittering surface, many secrets lurk. Mysterious tremors that shake the ground are growing worse by the day. Nakhon's troubles give Plum a chance to fulfill her own New Year's wish: to do something big and meaningful with her Guardian powers. But how far will she have to go, and what will she have to give up, to make that wish come true?
