Query: Layers of mystery -- Very Exciting Read!

If you find the average mystery/thriller novel too grim with grisly murders and lots of gore, and prefer more "depth"-- you'll most likely enjoy Mary Stewart's style. She adds a romantic twist, and makes the girl Linda Martin very relateable. Most noteworthy is how "real" the characters seem--I felt as though I had actually met them, and I admit, developed a slight crush on one of the characters...As far as suspense goes, I usually pride myself in being able to guess what happens next, but I was often caught off guard. It really picks up speed in the second half--and is more exhilerating than watching a action movie (at least in my opinion). I finished at 3AM in the morning, feeling that Stewart is very talented and fluid with language; sometimes I stopped just to re-read how beautiful her phrasings were. All in all, you will be guessing until the very last paragraph!
