Oddly enough, getting stuck in airports seems to be a common thread! I was first inspired to pick up writing again after being stranded in an airport due to a cancelled flight. The resultant book - about a hotel inspector - was terrible, but it rekindled my love of writing. The next time I was stranded in an airport, I started writing about the experience, and wondered what character might best benefit from being in that situation. And that's when I hit upon the idea of an immigration minister, trapped in an airport.
