A lost grimoire. A dangerous new enemy. And a powerful magical weapon that could destroy the world.
Jayne Thorne, CIA Librarian, is back for another exciting mission. When her mentor goes missing, Jayne is sent to Paris to find him, only to land in the crosshairs of a deadly terrorist organization and their diabolical weapon, a mysterious poison that renders their enemies powerless.
Fighting to combat this weakness, Jayne struggles to make peace with her sister, who has been hiding the truth of their family history for years, and overcome difficulties with her shifter boyfriend, who can’t quite sync up with Jayne’s new powers. Even worse, the terrorists demand she locate a necromantic grimoire in France, or they will kill her mentor.
As Jayne hunts for the grimoire, she unlocks the secret to summoning the Master of Shadows-a long-dead master magician possessing a dark and destructive magic. With this lethal power unleashed, she must protect her team from the worst magical threats they’ve ever faced . . . or suffer the deadly consequences.
Contains mature themes.

A librarian. A spell book. And a terrorist organization set on enslaving the world.
Librarian Jayne Thorne enjoys her quiet life of tea and books. That is, until she finds a spell book in the Vanderbilt archives that accidentally gives her access to a magical dimension.
Now she’s hunted by a magic-wielding terrorist group called the Kingdom, and the only way for her to survive is to team up with a secret branch of the CIA. Her first mission: Go undercover at Trinity College Library in Dublin to discover the identity of a Kingdom member and determine if the Book of Leinster is actually a magical necromantic grimoire.
With the help of a handsome Irish kickboxer, Jayne uncovers the truth of her unexpected spell book: The Irish manuscript is one of five grimoires that can raise five dead, master magicians, and secure their totems of power. With these totems comes the power to control the world.
But the spell book isn’t the only thing with secrets in Jayne’s new life. Danger lurks in every corner and Jayne must rise to meet her fated role . . . or perish alongside the rest of the world.
