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. ( )

This book`s cover is horrible.
And its contents is also strange.
This story is completely different from our real world,so it is future world story.
Harl is an astronaut.
He have to achive project X in space.
He takes a long time to achive project X.
So when he returns to the earth,a state of the earth change completely. ( )

Harl loved Ellen.And she loved him too.But they had to leave.
Because they were scientist,they thought works were more important than love.
I was very sad because Harl can't stay with Ellen long time.
I think love is more important than works!! ( )

Two scientists are main characters of this story.Their names are Harl and Ellen.They talked about the future of the earth.But one day, for their study they were separated.Harl decided to leave the earth to resarch telepathy and Ellen decided to stay on the earth.After Harl's study He returned to earth. However the earth was･･･
After I read this book I want to use telepathy.I think it is cool.and it was a very interesting SF story.I want to watch the movie of this story. ( )

The story is set in the earth of future. Harl and Ellen are scientist. They study to help everyone.
They love but they have to apart from each other because of their field of research are different.
Harl who is hero of this story make a study of telepathy. If people use telepathy, they can know other's thinking.
But I think it is bad. Because I hate being known all of my thinking. And possibly Communication disappear.I think this story is thoughtful. ( )

Be too far apart from reality,I did not feel that I was interesting.Because the book of such a genre remains and does not read,Comparison is not possible.I thought that I would choose a favorite next . ( )

This is a science fiction story about the human`s "telepathy".
After I read this. I felt so scared.But some people says already human has telepathy.

I am interested in telepathy.If everyone has real telepathy in the future,people will be ''like human''.I think people will lose humanity.So I disagree with Ellen. ( )

This story was little difficult for me.
I can not understand the story after reading.
The story about ..time srip? ( )

This is SF story.I think same thing is happen when same situation occur in real. ( )

This book is SF story. If you read this book, you could understand fear of telepathy. ( )

I like SF story. But I'm unsatisfied because none becomes be happy. ( )

I f you like science fiction story,why don't you read this? ( )
