[BIBLIO] Mary Stewart

[paigenumber]

As far as I know, Mary Stewart was a prolific writer.  Yet it seems as if I've already read most of them.  The following is a list of her books that I have read or currently have a copy of.  I would appreciate it if anyone knows of any other books and include it in the list:

1. Wildfire at Midnight
   
2. Madam, Will You Talk?
   
3. Thunder on the Right
   
4. Nine Coaches Waiting
   
5. The Gabriel Hounds
   
6. Airs Above the Ground
   
7. This Rough Magic
   
8. The Moon-Spinners
   
9. My Brother Michael
   
10. The Ivy Tree
    
11. Touch Not the Cat
    
12. A Walk in Wolf Wood
    
13. Thornyhold
    
14. Rose Cottage
    
15. The Stormy Petrel
    

She also wrote the Merlin books:

The Crystal Cave
The Hollow Hills
The Last Enchantment
The Wicked Day

I am unfamiliar with her juvenile fiction books.  Have I missed anything?  I would love to find any other books she may have written.
