Summary

Nothing quite prepared telepath Larry Greenberg for mind-to-mind contact with an alien. In the interest of science, Larry tapped the mind of Kzanol - and that was his first mistake. 

Kzanol was a thrint from a distant galaxy. He had been trapped on Earth in a time-stasis field for two billion years. Now he was on the loose, and Larry knew everything he was thinking. Thrints lived to plunder and enslave lesser planets - and the planet Kzanol had in mind was Earth!

Better to be read

I do like Larry Niven's books. I feel that this story, even though it was very well read might actually be better in the written version. If you enjoy it then you should give Protector, a book by L. Niven and Jerry Pournell, a read.

How annoying!

This cuts off in the middle of a sentence! Just ends! Clearly not the end of the book, just incomplete!

good book

love the series. good reading - although he has a low deep voice for some characters - and all of the narration. if you are traveling in a car with road noise it blends in completely. so don't listen while driving and all is wonderful.

Old school SF, terrific voice actor

Larry Niven's "known universe" is well portrayed in this story. I read it 55 years ago as a boy, yet hearing it again today, it is fun to contrast the small but important differences in today's future and the future of the story. Spaceships were wholy human controlled and manually, whereas we today know such inventions would be computer-controllled. Yet, "hand phones" were anticipated correctly, though not as widespread as they are today.

Bradford Hastings should be given special honors. He is able to nuance every character into a unique personality with his voice. He is as good a voice performer as I have heard. I will be looking for his work in the future.

Fun, but Dated

I read this as a young adult in the 70’s. It’s funny now to hear Niven’s anachronisms; cigarettes and pipes in a spaceship, subservient women, actual motion picture film for surveillance, etc. But the idea of a race that can enslave all the galaxy via mind control, that’s still enticing. Enjoy.

very penjoyable.

personable. of Nivens first novels and an introduction to the known space universe,not I enjoyed the story, easier to get through than Protector. Not as long as his later efforts like the Ring world series.

Audible issues

Lots of missing sentences and abrupt cut offs. Seems to be an ongoing issue with audible but more pronounced in this book.

Stands the test of time

40 years after my first reading, this story holds up. I enjoyed the audiobook as much as the written.

ages well

other than the Tom Collins, paperback reference and the hilarious smok8ng in spaceships, this ages well in terns of science and story. Larry Niven"s first book is a doozie. someone should adapt this for film
