I have converted my friend Li to the greatness of Mary Stewart. MWAHAHAHA! She loved Nine Coaches Waiting so much that she's now rushed to order more Stewart. I've told her she has to read This Rough Magic next. :)
And Alicia Paulson, creator of the very popular craft blog Posie Gets Cozy, has been reading Rose Cottage and Thornyhold. She loved them, of course. She says Rose Cottage "was the perfect book to read on a blanket under the shade of a tree in the Shakespeare Garden (which is where I read it). Good one."
