The Kite Runner - Khaled Hosseini

Groomed by Laurie Matthew

A book I will never get out of my head is Fairest. I do not remember the author but it is an amazing book.

Get Me Out Of Here By Rachel Reiland really spoke to my heart my story is a little different to hers but suffering from borderline personality disorder makes its hard to feel emotionally connect to someone but I felt connect to her as I read her book. I am glad someone other than Susanna kaysen spoke out about the disorder (not that I have anything against Susanna kaysen) its just I felt I could relate more to Rachel Reilend and her story

Another book I related to and found inspiring was Life In Rewind By Ed Zine. If you have lost your mum or have battled with OCD I think that you should read this book.

I have not read many, but one that was immensely simple and inspirational and made me realize the unlimited potential that each human has within him/herself was:
Jonathan Livingston Seagull, by Richard Bach

Ender's Game by Orson Scott Card or Cryptonomicon by Neal Stephenson

A Thousand Splendid Suns - Khaled Hosseini

It shows how much women suffer and endure, and that behind every hardship, there is a sun waiting to shine on.

Wuthering Heights- Emily Bronte

It's very dark but if you truly understand the art behind it, it's one of the most inspiring books I've read.

Watership down by richard adams was the first to affect my thinking

rita hayworth and the shawshank redemption by stephen king is up there.

plus the hunger games trilogy, read all three in a matter of a few weeks
