The People on Platform 5

Every day at 8 : 05, Iona Iverson boards the train to go to work. As a seasoned commuter, there are rules to follow : You must have a job to go to. Don't consume hot food. Never speak to strangers on the train. Iona sees the same group of people each day, people she makes assumptions about and gives nicknames to, but never, ever talks to. Then, one morning, Smart-But-Sexist Surbiton chokes on a grape right in front of Iona.
Too-Good-To-Be-True New Malden saves his life, and this one event sparks a chain reaction. With nothing in common but their commute, an eclectic group of people learn that their assumptions about each other don't match reality. But when Iona's life begins to fall apart, will her new friends be there when she needs them most ?
