Lost in Time and Space: An Unofficial Guide to the Uncharted Journeys of Doctor Who

 is a guide published by Hasslein Books and written by Matthew J Elliot which takes events heard or spoken about onscreen and places them chronologically between the episodes''. ''

Publisher's summary
BBC's immensely popular Doctor Who series, featuring an extraterrestrial Time Lord exploring the universe aboard a time machine resembling a police call box, is a significant part of British pop-culture and a cult favorite worldwide. The series has changed radically over the years, with thirteen actors portraying the Doctor to date, and with more than 50 companions joining him on his adventures.

But the show's 800 televised episodes (so far) are just the tip of the iceberg, as the Doctor has referenced countless encounters never expanded upon onscreen. After five decades of time-traveling adventures, you might imagine you knew all there was to know about the greatest hero in all of time and space, but it turns out he was living another life entirely while we weren't looking. This is the story of that life. 

Notable features
Includes a Foreword by Alan Barnes, the author of the animated Tenth Doctor adventure The Infinite Quest, and a writer and editor for Big Finish Productions' audio dramas featuring five of the Doctor's earlier incarnations.
