Trevor and his sister Farrah are in the fifth and fourth grades. How did they get a time machine? And why does everyone think they are the key to saving the galaxy?
This book is a great gift for boys and girls to get them interested in science. It is also fun for adults who enjoy fantasy, science fiction, and high level discussions of some of the greatest ideas ever discovered.
