How to Travel Through Time
Avon Books, 1993
If you think that time travel is something that happens in comic books and movies, this book will open a whole new world of excitement for you. You'll discover how you can live the thrill of sailing an old pirate ship, or jump into the future to visit outposts on other planets. This book will tell you about real people who claim to have experienced time travel--and give you some ideas on how you can make such a journey.
Originally published in softcover by Avon Books for ages 8 and up, it was inspired by a long-forgotten book that James M Deem discovered one day in a used bookshop in England: Practical Time Travel by Colin Bennett was published in 1936. Readers then (and now) were interested in the possibilities of time travel.
