I have enjoyed some Mexican authors. I enjoy their bizarre and whimsical view of death, life, fate, etc. It's been awhile and I don't remember their names.
I like authors who give a strong sense of place, therefore I read a lot of authors who are local to me: Tony Hillerman, Jake Page, and Stewart Woods for instance. I grew up in the desert southwest.
I've never thought about whether I would be more or less likely to read a foreign writer. I wouldn't seek them out, unless I planned to visit their part of the world. But that's something I've only dreamed about so far. I do think that's a good way to get to know a place. With that in mind, do you know any good authors from the Mobile, Alabama area? That's the next place I'm going to write about.
