Joe Haldeman is a Vietnam veteran whose novel "The Forever War", written a few years after his discharge and influenced by his combat experiences, won both the Hugo and Nebula Awards as best novel of the year. Years later, his sequel to that memorable novel, "Forever Peace", also won the Hugo and Nebula Awards and was cited by "Publishers Weekly" as one of the Best Books of the Year. He has written many other novels, including the best-selling "Worlds" trilogy, and has served twice as President of the Science Fiction Writers of America. When not writing prize-winning and best-selling novels, he teaches writing as an adjunct professor at the Massachusetts Institute of Technology. Martin Harry Greenberg has edited more than 1,000 anthologies of science fiction, fantasy, mystery, and other genres, and has become renowned for his ingenuity in developing books written around a theme, and his ability to fill them with stories of high quality. "Booklist" has written, "Greenberg's choices are impeccable," and "Library Journal" has praised his volumes for "Sheer enjoyability . . . provokes everything from meditation to laughter."
