Book excerpt: A warm tribute to the late Hal Clement, the writer, and to Harry Clement Stubbs, the man behind the pseudonym, this book brings you remembrances by friends and colleagues, a previously uncollected Hal Clement short story, an original story by Walter Hunt, an interview by Darrell Schweitzer, a reminiscence by his widow, Mary Stubbs, and many reminders of the many ways he affected the lives of fans, students, and fellow writers. The contributors to the book begin with the members of the writers' group he mentored, Hal's Pals: Leslie A. Greenleaf, Jr., Sherry Briggs, Tania Ruiz, Anne Warner, Steven F. LeBrun, Matthew Jarpe, Ramona Louise Wheeler, and Lance Dixon. From the professional community come: Ben Bova, Allen M. Steele, Walter H. Hunt, Anthomy Lewis, Jeffrey A. Carver, Michael Swanwick, Stanley Schmidt, Julie E. Czerneda, Isaac Szpindel, Jack Williamson, Michael A. Burstein, David Gerrold, J. Michael Straczynski, Darrell Schweitzer, and Joe Haldeman. All proceeds will go to Milton Academy, the school where Harry taught science for thirty-eight years, and Joslin Diabetes Center, important to Harry because he had the disease.
