A DISCOVERY OF WITCHES is a bold and romantic thriller that uncovers a secret underworld of vampires, witches and daemons hiding in plain sight for fear of persecution by humans. Brilliant historian Diana Bishop is a witch denying her own heritage. But when she unexpectedly calls up an ancient, bewitched manuscript from Oxford's Bodleian Library, she finds herself thrown into the heart of a dangerous mystery – and into the path of the enigmatic geneticist and vampire Matthew Clairmont. Across three distinctive and gripping seasons, Diana and Matthew's quest to solve the mystery of the book and their own long-prophesied connection to it throws them into the path of dangerous enemies.
