A Deadly Transaction, A Dangerous Game

When Alastair Stone’s former apprentice Verity approaches him with the story of a drugged and caged Changeling she spotted at a magical black market in Europe, Stone is quick to offer his aid to locate the victim.

Once on the Changeling’s trail, though, Stone and Verity soon discover they have stumbled upon the tip of a horrific iceberg—a shadowy organization operating deep underground, kidnapping specifically-targeted Changelings for an unspeakable fate.

Drawing more of their group into the search, Stone and Verity continue tracking the organization despite growing danger—but whoever lurks at its root always remains a step ahead, almost as if taunting them.

Finally, in a desperate effort to outsmart their foes, they hatch an uncertain and perilous plan to track them to their lair, reluctantly using an unlikely volunteer as bait.

But there are things they don’t know that make the risk higher than ever—and if their enemy learns of the plan, it could mean not only failure, but the loss of a valued ally.

Prepare to lose yourself in this #1 Amazon-bestselling urban fantasy series listeners are calling “Unstoppable” and “A major winner!” Once you enter the world of Alastair Stone, you won’t want to leave.
