This takes place in the not too distant future where instantaneous transfer to the galaxy is discovered accidentally. The basic premise of the story is when the team of galactic explorers run across another intelligent species.
Jacque and Carol are the most frequent protagonists used in the story. Their exposure to the alien race has an impact on both of them. They use a possibly intelligent species as a telepathic mind bridge thus the title of the book. The story also illustrates some of the dangers of telepathic communication.
The book is lauded as being a classic and perhaps it is but it didn't do a whole lot for me.
It's worth reading but it certainly wasn't a book that was going to keep me up at night to finish it. I enjoyed his Forever War much more than I cared for this book. Worlds also held greater appeal for me.
This book may have been received free of charge from a publisher or a publicist. That will NEVER have a bearing on my recommendations.
