When Harl returned to earth after an interval of eight years, one hundred years passed in the earth and the world changed dramatically.
This story is exciting and horrible.
I think technological advance isn't only good.
After I read this story I thought about the earth of the future.
In 2129, what will happen in the earth? ( )

I thought this story was very horrible when I saw the cover picture,but this story wasn't very horrible. It is SF. And this book tells us that science made by human is great but horrible. The story makes us think about peace in the future deeply.
The hero is Harl. He plans to leave Earth for eight years. But when he and some people returned to Earth eight years later,one hundred years passed here!
The heroine is Ellen. She and some people do project X. This project makes creature become telepaths!! Do you want to live in this strange world? ( )

on the earth in the future,humans planed the ploject X.
The ploject X is what makes humans telepath.
And many times later,on the earth...
This story is little afraid,SF story.

This story is interesting.
Because humans tried to makes them telepath is very strange.
why did humans wont to complete project X so?
This story's last is a little uninteresting. ( )

I was a little afraid of the cover of this book, but the content is thrilling and exciting.
A heroine of the story, Ellen, says to want to return to Earth.
But it has passed 100 years in Earth since they leaved Earth.
So her family and friends have already been dead.
However, Ellen and a hero of the story, Harl, decide to return to earth...
The story was deeper than I thought. ( )

Harl and Ellen are scientist, Harl and Ellen falled in love. But Harl left the earth to travel in the spece, he was going to return the earth in 2129. Ellen stayed the earth. When he returned the earth, everything was change...
I thought Ican't travel in the spece. I can't image that Nothing in the earth. No family,no friend is lonly for me. I didn't understand Harl left Ellen, she is poor. ( )
