James Grippando earned a law degree from the University of Florida and practiced for a large Miami firm for twelve years. But his true love, other than his family, is writing. Readers are most likely familiar with the New York Times bestsellers in the Jack Swyteck series, which began in 1994 with “The Pardon.” However, a novel about the Florida sugar industry was always in the back of Grippando’s mind. Sally Bissell reviews the suspenseful result in “Cane and Abe.”
