Help me make a reading list, please

After going to hear an excellent Irish-US group last night, I'm in a mood to spend some time reading about Ireland.

When I pick books out for myself, I usually gravitate to historical fiction - which is great; I loved the Irish Country Doctor books, but I have no idea what good contemporary stuff is out there.

Basically what I'm looking for is the Irish equivalent of Ian Rankin's books, something with a great story, with a setting that's almost a character itself. YA and adult fiction are both good, but I try to avoid depressing books.

Any suggestions? They'd be much appreciated.
