I loved it - not at all what you'd expect from beginning, it builds and is actually an incredibly poignant tale by the end- I felt it dragged a little in the middle around the maze section as the story doesn't really develop there, and some might not even realise how far it goes, with some of the early possible endings.
But it has some really insightful and affecting writing- was surprised how young the author was when he wrote this, from the supporting documentation! Really beautiful, although much left very ambiguous.
