Francesca Lia Block (born December 3, 1962) is an American writer of adult and young-adult literature: fiction, short stories, screenplays and poetry. She is known best for the Weetzie Bat series — named after its first installment and her first novel, which she wrote while a UC Berkeley student, Weetzie Bat (HarperColins, 1989). She is known for her use of imagery, especially in describing the city of Los Angeles. One New York Times Book Review critic said, "Block writes about the real Los Angeles better than anyone since Raymond Chandler." She won the Margaret Edwards Award from the American Library Association in 2005 for her contribution in writing for teens.
