The content itself - the plot, as it were - is vaguely Adams-esque. But... the prose is not up to standard, and he's reformatted the "entries", such as they are. I do not know why, but it makes things fairly unpleasant.

So. Um, read it, and then try to forget how it feels, and remember only what happens. What happens is alright by me. It's just... Eoin Colfer is a lovely author, but he is very different from Douglas Adams, and what he writes does not fit.
