A recluse software programmer has created an extraordinary online dating service called One Match that pairs its customers with exactly one other person using its advanced algorithms. The only catch is that the paired couples must meet in-person to discover each other’s identity. Claire Moore is a Londoner in her late twenties who is frustrated by the grind of online dating and wonders if she’ll ever meet someone who’s right for her. Urged on by her friends, she finally gives One Match a chance one lonely evening. The outcome of her match shocks her and sends her on an adventure to find out who she really is and what truly matters in her life.
