3.5 - 4 stars. Overall good, but definitely a 'Twilight' for grown ups. Instead of teens at a high school, they are adult professors at Oxford University. He is a vampire, a she a witch and his obsession. This is just part one (of an unknown number?) in a series where the H/h's story will continue. Many questions remain unanswered. The pacing reminded me a bit of Outlander with its rich details of each character and surrounding, detailed accounts of past events...etc. But for me it was too much (I didn't stick with Outlander, btw.) In places this story moved so slooooooow I thought of quitting. It's 600 pages (24 hours on audio) and so I expected more things to actually happen. Still, I was intrigued by the core story of a lost magic book and a war looming enough that I may actually continue with this series.
