David Klass is an acclaimed screenwriter of such movies as Walking Tall and Desperate Measures, and is the author of many popular YA novels, including Second Impact, co-written with his sister, Perri Klass, and Grandmaster. He lives in New York City. Klass grew up in a family that loved literature and theater-his parents were both college professors and writers-but he was a reluctant reader, preferring sports to books. But he started loving the adventure stories his parents would bring home from the library-particularly Jack London, Robert Louis Stevenson and Alexandre Dumas. After his sister twice won a story contest in Seventeen magazine, Klass decided he would win it too, and when he was a senior in high school, he did, publishing his first story, "Ringtoss," in the magazine. He studied at Yale University, where he won the Veech Award for Best Imaginative Writing. He taught English in Japan, and wrote his first novel, The Atami Dragons, about that experience. He now lives in New York with his wife and two children.
