When he absolutely must wed, he assumes, it should not be too hard to find a suitable young woman.

Demure Abby Fairchilde has just about the same attitude toward marriage: Why get herself in a tizzy over it when everyone else is worrying her her? But when their paths cross by chance, Lord Darlington and Abby find themselves listening to the happy notes of a love song - a song they did not know existed....
