What has the author O A Overland written?

You're asking about the author O.A. Overland, but I'm having trouble finding much information about them. It's possible this is a pseudonym or a less well-known author.

To help me find more information, could you please provide some additional details? For example:

* What genre do they write in? (e.g., fiction, non-fiction, poetry, etc.)

* Do you remember any specific titles or books they've written?

* Do you know anything about their background or nationality?

With more information, I can search more effectively and hopefully provide you with some relevant details about the author.
