I live in Salt Lake City and our public library has a large foreign language section. I checked it to see if they had any of the authors she mentioned, and they did. I just checked to see if they have anything by Jacek Dukaj, and unfortunately, they don’t. Have you contacted bookstores in your area? Large bookstore chains can usually order a book, if they don’t have in their inventory.

Good luck in your search. And it sounds like your wife is lucky to have such a considerate husband like yourself.
