Billie Keller, head of the FBI’s Magical Threats Division, has a knack for finding trouble. This time, it’s electric.

Literally.

Alongside her bow-wielding pixie partner Onyx, Billie is chasing a new breed of danger—genetically modified superhumans wielding the raw force of nature. They’ve already gone toe-to-toe with fire. Now the storm is coming for them.

Izzy, their infomancer, is ready to take another crack at hacking the company behind the experiments. A fortune-teller, a potion maker, and a no-nonsense trainer are standing by with backup. And then there’s Dorian, Billie’s sharp-tongued, sentient blade.

But lightning strikes again.

To survive, the team will need every skill they’ve got—stealth, shooting, investigation, and plenty of snark from Onyx. Even then, taking down an enemy with the power of a thunderstorm in their fists may be more than anyone can handle.

Good thing impossible missions are exactly what the MTD was made for.
