A whole lot of critical events happen in this volume of Fruits Basket! I recommend not reading it until you have read the preceding twenty volumes, but who's to say you won't find it heart-pounding and a good read? Anyway, I won't tell you what happens because that would just be spoiling the fun. It is a good book, the ending is kind of shaky, though. But Natsuki Takaya always leaves me wanting more.
