The #1 New York Times bestselling FBI Thriller series returns with another tour de force in which Agent Sherlock risks losing her career—and her sanity—over a case that is more complicated and twisted than any she’s ever encountered.

Special agents Nicholas Drummond and Michaela Caine take on a ruthless mastermind in the fifth highly anticipated thriller in the New York Times bestselling A Brit in the FBI series.

It’s Bastille Day in France, and the private French space agency Galactus—France’s answer to Space X, owned by the eccentric treasure hunter Jean-Pierre Broussard—has just sent a satellite payload into orbit. Billed as a “communications” satellite, it harbors a frightening reality: a nuclear electromagnetic pulse has been hidden aboard.
