"Race To The Finish : After Kitty's shocking revelation, Tta goes to me[e]t with her again, but all he finds is a note telling him to come back in four days, or to her, 287 years. In the meantime, Dana gives Tta some big news: She's prepared a finishing move for him! But there's a catch: the book on how to perform the move is hidden in a box in the monster-infested castle ruins below... a challenge even before Dana sends him to a distant starting point. Can Tta complete his mission and make it back in time to see Kitty once again?" -- back cover.
