Although thirty-three-year-old Kara Moon loves her hometown of Hartmouth in Cornwall, she has always wondered if she should have followed her dream of going off to study floristry. But she couldn't bring herself to abandon her emotionally delicate single father, and has worked on Ferry Lane Market's flower stall ever since leaving school.

When her good-for-nothing boyfriend cheats on her and steals her life savings, she finally dumps him and rents out her spare room as an Airbnb. Gossip flies around the town as Kara welcomes a series of foreign guests to her flat overlooking the estuary.

Then an anonymous postcard arrives, along with a plane ticket to New York. And there begins the first of three trips of a lifetime, during which she will learn important lessons about herself, her life and what she wants from it - and perhaps find love along the way.
