Children's book illustrator Irina McGovern enjoys a quiet and settled life in London with her partner, fellow American expatriate Lawrence Trainer, a smart, loyal, disciplined intellectual at a prestigious think tank. To their small circle of friends, their relationship is rock solid. Until the night Irina unaccountably finds herself dying to kiss another man: their old friend from South London, the stylish, extravagant, passionate top-ranking snooker player Ramsey Acton. The decision to give in to temptation will have consequences for her career, her relationships with family and friends, and perhaps most importantly the texture of her daily life.
