Brilliant historian Diana Bishop (Teresa Palmer, Hacksaw Ridge, Warm Bodies) is a witch denying her 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 enigmatic geneticist and vampire Matthew Clairmont (Matthew Goode, Downton Abbey, The Crown). Matthew is driven to solve the looming threat of magical creatures' decline and believes that the lost manuscript could answer the mysteries of their existence. Their unlikely alliance to find the book before it falls into the wrong hands-and their deepening relationship-threatens to violate age-old taboos and shake the fragile peace that exists between the species. Adapted from Deborah Harkness's bestselling trilogy of novels, this romantic thriller series is "pure catnip for fans of this genre" (TVGuide. Com). The outstanding supporting cast includes Alex Kingston (ER), Lindsay Duncan (Sherlock), Owen Teale (Game of Thrones).
