FTC Disclaimer: I received a free copy of this book for review through the Goodreads First Reads program. 
 When historian and reluctant witch Diana Bishop stumbles upon an alchemical manuscript thought lost hundreds of years ago, she gains the unwanted attention of every witch, vampire, and daemon in the world. They suspect the manuscript holds the key to the secret of their existence and will kill to keep it away from the other creatures. But Diana thinks it is much more important than that and is willing to overturn centuries of tradition in order to protect it and keep her vampire lover. 
 As a scholar myself, I thought this book started off very strong. The mystery surrounding the book is gripping, Diana is a compelling character, and the nature of the three types of creatures is intriguing. However, I did not find the romance between Diana and her vampire, Matthew, convincing, and halfway through the book the plot comes to a screeching halt in order to deal with the budding romance, which became a bit too Twilight-esque for my taste (though at least the characters do actually have physical relations rather than the vampire refusing "for her own good" to do more than kiss her). I was so much more interested in the history, manuscript, and mystery that I found the romance and its tendency to take over the entire story annoying. 
 I understand this is going to be a trilogy, and I will more than likely pick up the next couple of books to see how the story ends.
