What has the author Wolf Kruger written?

There doesn't seem to be a well-known author named "Wolf Kruger." It's possible there's a typo in the name, or the author may be less known or publish under a different name.

To help me find the author you're looking for, could you provide more information? For example:

* Do you know what genre they write in? (e.g., fiction, non-fiction, poetry, etc.)

* Can you recall any specific titles or keywords from their work?

* Do you know where they might have published their work? (e.g., specific magazines, websites, or publishers)

With more information, I can try to identify the author you're looking for.
