Summary
From the back cover US edition
Who is the Vulcan named Xon and why did he replace Spock as Enterprise science officer?
What was Gene Roddenberry's last story concept for Star Trek?
Why wasn't there a fifth season "Q" episode of Star Trek: The Next Generation?

These are among the questions answered in Lost Voyages of Trek & The Next Generation, a comprehensive guide to the greatest unfilmed Star Trek adventures spanning the show's 26 year history. Among the tales:

* Trek classic: "He Walked Among Us," written by Norman Spinrad and Gene L. Coon
* The unfilmed Star Trek movies: including a Gene Roddenberry time travel adventure and "The Billion Year Voyage" by Robert Silverberg
* Star Trek II (the series): "In Thy Image," "The Child," "The Savage Syndrome," "Kitumba," "Practice in Waking," "A War to End Wars," "Devil's Due," "Deadlock" and others.
* Star Trek: The Next Generation: "The Immunity Syndrome," "The Crystal Skull," "Blood and Ice," Gene Roddenberry's "Ferengi Gold" and "I.Q. Test."

In addition to detailed summaries of these Star Trek adventures, you'll meet many of the individuals behind them and learn exactly why they never made it to the screen. Some of Star Treks best stories have been left untold, but Lost Voyages boldly takes you on a guided tour through two generations of adventure.

From the back cover UK edition,
Within its thirty year history, from  to Voyager, there have been nearly 300 filmed Trek adventures. Whilst these were being written and produced many ideas were discussed, plot lines planned, endings changed.

Lost Voyages of Trek and The Next Generation serves as an in-depth guide to the Trek episodes that never were, from Trek Classic's "He Walked Among Us" through the scripts written for the aborted 1970's series Star Trek II. There are also details on alternate – and never seen – feature films, including Starfleet Academy and Star Trek VII, and the lost voyages of The Next Generation.

For the Trek fan these lost voyages play an integral role in the history and development of all things Trek.
