While there's no widely recognized author with that exact name, there are a few possibilities:
* Typo: Perhaps you meant Margaret Atwood or Margaret Laurence. These are well-known Canadian authors who share a similar name.
* Less Known Author: There might be a lesser-known author with this name who hasn't achieved widespread recognition.
To help me find the right author, please tell me:
* What kind of books do you think she writes? (e.g., fiction, non-fiction, historical, romance, etc.)
* Do you have any specific titles or works in mind?
* Is there any more information about her you can provide?
With more details, I can hopefully find the right Margaret Penner Toews for you!
