YA novels set in Ireland

Happy St. Patrick's Day! In the spirit of the holiday, here are a few YA books set in Ireland. Have you read any of them? What do you think about reading books set in another country in general? I don't really mind where my books are set, as long as I can connect with the characters and understand the setting, but I've read that a lot of readers prefer to read books set in the country they are from or live in.
