Actually, I have both!!! (big surprise
)
The Angel of Mill Street has fabulous pictures. I'll have to get it out, and read it again. It's a sweet story. If memory serves, they don't really mention it's a Newf, but when you see the pictures, there is no doubt.
Newf by Marie Killilea, is wonderful as well!!! It's one of the books I use on Pet Therapy visits.... kids love it. The illustrations are beautiful.
I'm currently reading "With Love from Karen" also by Marie Killilea, and I'll report as soon as I've finished it! (Hint, it's very special, and you need at least one box of kleenex near by)
