THE DISCOVERY OF WITCHES. Deborah Harkness is a new writer from the US. The book attempts to bring an adult feel to the subject matter that Twilight and Harry Potter fans. It did feel a bit like a fusion of the two series...except I think that's a bit of an insult to JK Rowling, who's overall plotting, theme and narrative is exceptionally rich and inventive...unless the author had previously watched True Blood, which has a very similar premise. Nothing much happens, but the hero, Matthew, a vampire is worth following...sexy and dangerous.
