I liked the romance aspect of this novel, but it was totally eclipsed by the plot and I LOVED it. I liked how the author used a 10 year old's science fair to describe String Theory and M Theory in layman's terms, setting up the reader for the possibilities that would unfold. My only gripe is the ending...I wanted this book to go on! I wanted to zip through the idyllic phase and get onto the meat of the preparations, etc.
