Extract: We Were Never Here by Andrea Bartz
Emily is on holiday with her best friend, Kristen, in the stunning mountains of Chile. It's heaven on earth - until, on the last night of the trip, Emily enters their hotel suite to find it covered in blood. Kristen claims a backpacker attacked her. She shouted, but no-one heard. She struggled, but he was too strong. She had no option but to kill him.
