Any potential reader of this novel must satisfy the proviso that they are ok with some very disturbing, graphic horror of the psycho-killer variety.
Once over that hurdle, this begins as a shipwreck scenario of 9 or so unremarkable people that becomes a tense cat-and-mouse game that thunders on at breakneck speed to the end. It is set in the Australian outback. The peculiar environment makes for a great setting that is unpeeled to the characters, with the reader accompanying their every step.
The periodic messages on their 'game machines' make this a page turner for the reader, with the characters drip fed information that unravels the motives of the game and what lies in store for them!
The ending to the bizarre and horrifying story has been resplendently crafted by Kishi, and rewards the reader for getting to the end.
