I read cozy and historical mysteries, a bit of Paranormal/UF, and to mix it up, I read science and gardening books on occasion.
This trilogy is on my mind lately because the third one is out this month. There are other books I could easily have chosen, but I've either used them already (Discovery of Witches) or have plans to use them for another day.
I find Deborah Harkness's writing to be incredibly effective at putting me where ever I'm meant to be: the Bodleian in Oxford, a folly of a hunting cottage in the wilds of Scotland, a castle is San Lucien, France or a ramshackle farmhouse in Madison, NY. In Shadow of Night it's 1590-91 London, Saint Lucien and Prague. For me, I might as well have been watching this book in IMAX.
