This was a very short, super-fast read. It's a dream-like string of 42 very brief "chapters," interspersed with atmospheric black and white woodcut illustrations--nothing like the cover, in case you were wondering--by the author's father, and divided into 3 parts. It tells the story of a man who was badly beaten and slipped into a coma as a result. The majority of the text describes his experience during his almost sleep-like state.
Anyway, back to the book . . . I have a confession to make. I didn't understand the ending. I was left feeling like everything was ambiguous. So I cheated, and asked Sam what it meant, and he showed me that there was a trick that explained everything. (Too bad the explanation was kind of a grade-school cop out.) And then I was able to go back to the two other tricksy parts of the book and crack the codes (whereas before this I hadn't even realized there was a code). Kind of wish I'd figured it out myself! But simultaneously glad I'm not still ignorant of the solution.
