The Guardian. My mother gave me my first Mary Stewart romance, The Moon Spinners, when I was twelve, and I couldn't decide which I loved most about it--the beautiful descriptions of place, or the romantic frissons. This combination, sometimes more successfully than others, makes her an author I still treasure (mostly in memory, because I read her books so often that my mind can just scroll through them at will). I wonder if my mother ever noticed that I took all her Mary Stewart books away with me....she had them practically memorized too, so perhaps not.
I'm so glad her books got reissued recently, and she found new fans!
And I loved her children's book, The Little Broomstick, and her vision of the Dark Ages, put forward in her Merlin series that beings with The Crystal Cave, had a huge impact on me.
Here's the one thing I hold against Mary Stewart--she made me feel inadequate about my inability to wear crisp linen dresses while traveling (see Madam,Will You Talk). (No matter how crisp a garment is when I put it on, almost immediately the rot sets in....)
