* The name is misspelled. Perhaps you are thinking of another author with a similar name. Could you double-check the spelling?
* The author is not well-known. If the author is less established, their work might not be widely available or listed in online databases.
* The author uses a pen name. Many authors use pseudonyms, so it's possible "P Newell" is not the author's real name.
To help me find the author you are looking for, please provide more information, such as:
* The genre of their work: What kind of books do they write? (e.g., fiction, non-fiction, poetry, etc.)
* Any other details you know: Do you remember any titles, characters, or a brief summary of their work?
With more information, I can help you identify the author and find their books.
