“Firefly proves once again that … British espionage fiction is the best in the world, and Porter is part of the reason why.” ―Lee Child, #1 New York Times bestselling author

From the refugee camps of Greece to the mountains of Macedonia, a thirteen-year-old boy is making his way to Germany and to safety. Codenamed “Firefly,” he holds vital intelligence: unparalleled insight into a vicious ISIS terror cell, and details of their plans. But the terrorists are hot on his trail, determined he won’t live to pass on the information.
When MI6 become aware of Firefly and what he knows, the race is on to find him. Paul Samson, ex-MI6 agent and now private eye, finds himself recruited to the cause. Fluent in Arabic thanks to his Lebanese heritage and himself the product of an earlier era of violent civil war, Samson’s job is to find Firefly, win his trust, and get him to safety.
A devastatingly timely thriller following the refugee trail from Syria to Europe, Firefly is a sophisticated, breathtaking race against time from an author who brings a whole new level of urgency to the genre.

“A classic chase thriller with an on-the-scenes look at the Syrian refugee crisis―it doesn’t get more contemporary than this.”—Joseph Kanon, New York Times bestselling author of The Accomplice

“A welcome return . . . Firefly seems ripped from the headlines and is both timely and terrific.”—Mick Herron, CWA Gold Dagger Award-winning author of Joe Country
