Kahlil Gibran. His book, The Prophet, was given to me when I was in my twenties. It became one of my most cherished books. Years later Laura discovered him as well, and she also loved his work and his poems. The book that had the most impact on her was Broken Wings. It is mentioned in the second book, Suicide at the Burj Khalifa, hopefully to be published in March 2019, if not earlier.
