The concept has everything going for it, but it is wasted in here. The book spends far too long exploring the possibilities of the scenario that such niceties as a plot have been completely forgotten. It's a mildly entertaining exposition on a 'what-if' nature of life and death theme, woven around some obscure references to paintings and some tediously over-long discourses on theology; but there is absolutely no storyline to engage your interest or make you care about the characters. The cat was the most interesting character in it. A complete waste of time.
