In "The Colors of Space," Marion Zimmer Bradley tells the story of Bart Steele, a human being who is disguised as a member of an alien species in order to discover the secrets of their space travel. This book is a science fiction novel set in the future, a time when humans can already travel faster than the speed of light and can reach the remote corners of the universe with the help of another type of beings called the Lhari. In the book, the Lhari help the humans to travel faster than light and go to the far corners of different galaxies but are unwilling to give their secrets to them. They constantly tell humans that they need to sleep in order to survive a faster-than-light space travel, but many people like Bart think otherwise. Bart joined a small band of people who want to learn the secrets of Lhari. He disguised himself as a Lhari and boarded a ship that was bound for the Lhari homeland. This was something that no human had ever attempted to do before and Bart had to survive it in order to prove that the Lhari are lying to human beings.
