The One, by John Marrs
I raced through this book. It has a fabulous premise: scientists discover everyone has a gene they share with just one other person, making them your perfect love match. And, of course, there’s a website that will find your match for a fee.
The narrative follows five different characters as the meet their match. Some of the characters I related to more than others, and it has the effect of a series of connected short stories. Full of twists and turns, and funny as well as exciting. A little over-dramatic for my tastes, but completely enjoyable.
