I read this when I was pre-teen around 12ish, my mum gave me her copy and I remember loving it! 
 Now I've found it on good reads and seen it's not a true story I'm really disappointed! I always thought it was a true story. 
 I was planning on re reading this this year but now I don't think I will. 
 I'll stick to my good memories and won't taint them by re-reading just in case I end up hating the book that I loved so many years ago.
