Hiding from her family history by becoming a leading scholar of Elizabethan science has served Diana Bishop well. She is on track to become one of the youngest scholars to obtain tenure at a top United States University. She is working on a research project in Oxford's Bodleian library when she meets Matthew de Clairmont.
The suave Monsieur de Clairmont is a vampire, older than the institution Diana has tied her future to. He immediately recognizes her as a witch - one who rarely uses her magic - and it is by her rarely used magic that she draws the attention of Witches, Vampires, and Daemons. The Ashmole Manuscript she calls for her research has been missing for decades when Diana recalls it from the stacks.
Rumor has it the missing manuscript tells the origin of Creatures. Diana's interest is only in the alchemical message of the text. But the fact that she can find Ashmole draws even more attention and ire when she refuses to hand over the document despite pressure from every creature of significant political power.
Matthew's interest starts with the manuscript but he finds Diana more and more compelling. When her own kind turns against Diana for refusing to provide the much-coveted Ashmole Manuscript, Matthew de Clairmont is her rescuer. The two remove from Oxford for her safety despite the Covenant of Creatures.
As they become more enraptured with one another Matthew and Diana seek to understand why the manuscript comes to Diana despite stronger magic's failure to call it forth. At the de Clairmont fortress in France Diana also discovers more about her magic and her personal history.
When the Congregation kidnaps Diana from the property - violating the de Clairmont sovereignty in their own lands - Matthew realizes how his life and that of the witch mirror her observations of the missing manuscript. He will violate his own laws to find and protect her and their growing relationship.
The more she learns about the Creatures' world the more Diana wishes she could return to the safety of her American ignorance. Her aunts--powerful witches in their magic-- do not have the political strength to protect her and her parents' magic - both rare and powerful - has been absent most of Diana's life.
Diana and Matthew risk more than just censure from the Congregation for an interspecies relationship. Something in the Ashmole manuscript has drawn the attention of the most powerful elements of their world and their ire. At heart, this is a romance with elements of The DaVinci Code and Charlaine Harris' Snookie Stackhouse series meant for mature readers with vivid violence.
