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. Luc 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.
