I teach 18- to 21-year-olds - the 'Harry Potter' generation. They grew up as voracious readers, reading books in this exploding genre. But at some point, I would love for them to give Umberto Eco or A.S. Byatt a try. I hope 'A Discovery of Witches' will serve as a kind of stepping-stone.

I found a 'lost' manuscript called the Book of Soyga that had once belonged to Queen Elizabeth I's court astrologer, John Dee, in Oxford's Bodleian Library. Everybody thought it was the missing key to Dee's interest in magic. Of course, it wasn't really lost. It was there, in the catalog.
