FaceMate

Alex Daugherty may be autistic, he may be dysfunctional, but he's a genius; and he's come up with a brilliant website that will match you--or anyone you've ever loved and lost--up with an exact double. With seven billion people on the planet to choose from, he's convinced he can do so with amazing accuracy. Ah, but what will happen to you and to your perfect double when they are found? Ben Atherton, the celebrated billionaire venture capitalist, a newly recruited backer of Alex's company, is about to find out.
FaceMate is a fast-paced tale of self-discovery populated by authentic, evolving characters and presented in polished prose that verges on the poetic without being baroque. It fits best into the upmarket fiction category, but is appropriate to and enjoyable by all segments of the reading public
