What has the author Roger F Krentz written?

It appears there's no widely known author named "Roger F. Krentz." It's possible the name is misspelled or refers to a lesser-known author.

To help me find the right author, could you provide more information? Perhaps:

* Genre: What kind of books do they write (e.g., fiction, non-fiction, romance, thriller)?

* Specific titles: Do you remember any book titles by this author?

* Other details: Anything else you know about them (e.g., their nationality, when they published)?

With more details, I can try to find the right author and list their works.
