What has the author Abbo written?

There is no author commonly known as "Abbo". It is possible you are thinking of a different name, or perhaps a different spelling.

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

* What is the author's full name?

* What kind of books do they write? (e.g., fiction, non-fiction, poetry)

* Do you know any of their works?

* Are there any other clues about the author you can provide?

With more information, I can help you find the author and their works.
