The Demon Hunt — Joseph Robert Lewis

Zelda Pryce gets more than she bargained for when she lets two strange and desperate travelers into her shop late one night. They don't look human, they claim Zelda herself sent them, and they're carrying the pieces to a long-lost arcane device that can predict the future!Suddenly Zelda is drawn into an ancient hunt for a dangerous woman with the power to create deadly plagues and turn any living thing into a tool, or a weapon. So with the help of the dashing Clive Caspian, special agent Yasmin Demir, and the arcane girl Jenny Baker, Zelda races from Siberia to China, and from Kenya to the very ends of the earth to stop her. But the only thing more terrifying than their enemy's plan is the discovery that Zelda herself set all these events in motion in the first place...
