James Swallow Marc Dane Series 4-6 Collection 3 Books Set (Shadow, Rogue, Outlaw):

Shadow:
A ruthless far-right terrorist is broken out of captivity. A mysterious bio-scientist with a terrible secret is abducted. A lethal virus threatens millions of lives across Europe and the Middle East. In a race against time that spans the globe, ex-MI6 officer Marc Dane and his partner Lucy Keyes are bound together in a desperate battle to stop the release of a deadly virus that will kill millions.

Rogue:
In modern espionage, every action has a reaction. One wrong move could sink an entire region into turmoil – even war.Ex-MI6 operative Marc Dane understands this better than anyone. Dedicating his life to protecting the country means he’s collected enemies, and a lot of them. But for those hellbent on bringing the West to its knees, each failed plot has one thing in common: The Rubicon Group, the elite private intelligence agency, and Dane’s employer.

Outlaw:
Gutted by the ruthless power brokers known as the Combine, the Rubicon Group is a shadow of its former self, its founder Ekko Solomon missing presumed dead and the members of its private security and intelligence team in hiding, framed for a terrorist atrocity they did not commit. For ex-MI6 officer Marc Dane, his friend and colleague Lucy Keyes, and the survivors of Rubicon’s Special Conditions Division, the future is bleak.
