Maybe we should inform them of the "bad end" waiting for them roughly 400 kilometers further on?
They are already *living* the bad end in the book this back cover comes from... I don't know whether to be appalled that Duck and Rabbit Teams are already killed off in brutal fashion (Rabbit Team's death is particularly artificial - maybe the author just hates them) or be happy that at least the author won't be able to come up with anything new to hurt them now that's he has already offed them...
I've heard about the K-On "deconstruction", and must say that compared to the Gup deconstruction the former sounds like heaven...
