This book was quite an unexpected brilliant discovery for me. The summary doesn't reveal too much so that the tale could be of any type.
Hmmm - every description I would write, would spoil the fun and excitement for you, so I leave it at that.
Just one more thing: although it's a short story, it has many twists and turns - and although the reader almost always believes to know how the tale will progress: it's wrong - or I'm just bad at guessing ;-).
