Angel Falls by Kathryn Casey
Patricia Hubbard
Ruth Robertson's life has inspired a book: ANGEL FALLS, by bestselling author Kathryn Casey. While the book is historical fiction, Casey relied heavily on research materials from the Ruth Robertson collection at the University of Texas-Austin's Harry Ransom Center. ANGEL FALLS starts with Ruth living in Brazoria County, Texas, near the end of her life, and her earlier years - including the expedition to the falls - form an alternating plotline.
