Mary Stewart was the first romance author I moved on to after I had read everything my library had by Georgette Heyer, which thus forced me to look around. A few decades later, I still love a bunch of Stewart’s books, and was thrilled when most of them finally appeared as e-books in the US, after a long wait. They are mostly in the $2.99 – $3.99 range, which is not bad for such great classic romantic suspense. Right now, though, The Moon-Spinners, which is one of my favorite Mary Stewart titles (among many favorites!), has dropped to $0.99 as part of Kindle US’s “Top fiction eBooks for $3.99 or less” sale. This means the sale price should be good through 12 Sept 2021. But I’d still buy it soon if you want it. It’s price-matched at Kobo US too, at least as of right now.
