Floor 99 unfolds between the 1982 massacre at Sabra and Shatila in Lebanon and life in the city of New York in 2000. Majd is a young Palestinian man who bears a scar from the massacre. In present day New York, he falls in love with Hilda, a dancer, whose wealthy family from Mount Lebanon thrived on the power of the Christian right wing during the Lebanese civil war - who were directly linked to the massacre at Sabra and Shatila. When Hilda decides to return to her village on Mount Lebanon to discover her roots, Majd is torn between mental images of the old enemy and his fear of losing her. He is forced to reflect on the painful events which took the life of his pregnant mother and turned his father, a teacher, into a rose-seller on the streets of Harlem. From his office on the 99th floor of a New York building, Majd's Palestinian identity seems ambiguous, especially given that he was born and has always lived in exile. The novel reflects on the power of love to cleanse hatred and brings the post-war Lebanese generation face-to-face with their ancestors.
