The Fourth Volume in the Acclaimed Series! For more than four decades, New York Times and USA Today bestselling writers Kristine Kathryn Rusch and Dean Wesley Smith wrote professional science fiction short stories that won awards and sold millions of copies. Now, for the first time, they collect together 120 of their science fiction short stories into a six-volume set called Colliding Worlds. Sixty stories total from each author, with ten stories from Rusch and ten from Smith in every volume. Volume 4 explores the rich meanings of the term “goofy.” Rusch offers up a guidebook for space travel with “Amelia Pillar’s Etiquette for the Space Traveler” and a very determined little girl in “Advisors at Naptime,” while Smith takes readers aboard the Titanic with Sherlock Holmes and contributes his Nebula Award-nominated tale of a vampire saying goodbye to a mortal lover with “In the Shade of the Slowboat Man.” A do-not-miss volume!
