As part of our "A Book That Changed Me" series, writers have told us about a book, pamphlet or essay which had a big impact on them, changing their thinking, or even their life.
So far we've had Gary Younge on how Langston Hughes' essay The Negro Artist and the Racial Mountain inspired him to become a writer. Now it's your turn.
To tie in with this series, we want you to tell us about writing that left a lasting impression on you. Did it change your outlook on life, or offer you some comfort and clarity in a difficult period? What books have helped form you as a person?
We're looking for 150-200 words on a book that changed you, with a photo of your copy of the book, however dog-eared. We'll publish our favourites on Comment is free, and you can read through other users' contributions throughout the summer.
To take part, just click on the blue 'contribute' button.
