The Stars in the Bright Sky by Alan Warner

This book tells the story of five Scottish girls and one's English roommate who get stuck in an airport while trying to go on a cheap holiday together. While the girls themselves aren't the type you'd necessarily want to hang out with (they love drinking and buying clothes), Warner does a great job of capturing six individual personalities--they seem vivid and real. Furthermore, the girls are clearly trapped by their surroundings, life in a small town, and poverty and dealing with it (or not) as best they know how (or can). It's a grim book, with a grimmer twist at the end, but all-in-all well done.
