From Publisher's Weekly:
In the first eight interrelated stories of the dozen that comprise her new collection, Binchy ( Circle of Friends ) introduces eight people who travel on a lilac-colored bus from Dublin every Friday night to spend the weekend in their hometown, Rathdoon. Each of the seven passengers and the bus driver is the protagonist of an individual story; taken together, the tales have the cohesion of a novelette. Though these people have known one another for years, they are totally unaware of the compulsions, anxieties, heartaches and dreams of their fellow travelers. As is gradually revealed, everyone on the bus has a secret; thus the stories have the pull of taffy: having finished one, the reader is hooked on discovering the essence of yet another protagonist's existence. Each story delivers a kick of surprise--and often more than one--as Binchy peels back the layers of her characters' lives with empathy, compassion and not a little humor.
I once wrote a story using hypertext that told the stories of a group of people on a subway train in Boston. I've thought of doing another one using people in a restaurant - where you could move from table to table and listen in on conversations and follow the people you were interested in.
