The writer Ray Bradbury, science fiction expert Forry Ackerman, and special effects genius Ray Harryhausen are world-famous for their careers involving tales of the imagination. Before anyone had heard of them, they were friends as teens and college-aged boys enjoying all that 1930s L.A. had to offer: getting celebrity autographs, watching blockbuster movies, and haunting hundreds of bookstores. As members of the Los Angeles chapter of the Science Fiction League, they belonged to a tight-knit group that was involved in the earliest science fiction conventions and the birth of cosplay.

This book follows the lives and careers of these three literary and film legends and tracks the origins of science fiction fandom. Each chapter builds a chronology of how their paths intertwined and ultimately connected to the beginnings of renowned fan conventions like Comic-Con. Devoted science fiction fans and new readers alike will learn how a young friendship launched three illustrious careers and changed the face of science fiction forever.
