What is a summary of the book Achillles by Elizabeth Cook?

"Achilles" by Elizabeth Cook is not a well-known book, and there is no record of a book with that exact title by that author. It is possible that:

* The title is slightly different. Perhaps you remember the title incorrectly. Try searching for similar titles or checking your source material.

* The author is different. Double-check the author's name, as there might be a different book with a similar title.

* It's a lesser-known book. It's possible the book is not widely available or published by a smaller press.

To help me locate the book, could you provide more information like:

* The year of publication (if you remember)

* Any details about the genre (e.g., fiction, historical fiction, etc.)

* Any other details about the book (e.g., cover art, characters, setting)

Once I have more information, I'll do my best to find the book and provide a summary.
