The People on Platform 5

Nobody speaks to strangers on the train. But what would happen if they did?

Every day at 8:05, Iona Iverson boards the train to go to work. Every day, she sees the same people and makes assumptions about them, even giving them nicknames. But they never speak. Obviously.

Then, one morning, Smart-but-Sexist-Surbiton chokes on a grape right in front of Iona. Suspiciously-Nice-New Malden steps up to help and saves his life, and this one event sparks a chain reaction... More here.

I shouldn't like this book so much, but I was curious and once I started reading I couldn't stop. Highly uplifting and a clever integration of completely different characters into one daily situation. Excellent.
