It all hinges on one kiss. Whether Irena McGovern does or does not lean in to a specific pair of lips in London will determine whether she stays with her disciplined, intellectual partner Lawrence or runs off with Ramsey, a hard-living snooker player.Lawrence is Irena's partner of nearly ten years. Ramsey is the ex-husband of a sometime friend, a once-a-year acquaintance to whom Irena has never paid a great deal of attention. Where Lawrence is supportive and devoted; Ramsey is flighty and spontaneous. Lawrence is emotionally withdrawn to the point of repression; Ramsey is fiery and passionate, but volatile. Using a parallel universe structure, we follow Irina's life as it unfolds under the influence of two drastically different men.
