The last orphan by Gregg Hurwitz

A heavily-armed counter-assault team, a convoy of tactical vehicles plus decoys, air support, a sedative more commonly used to knock out large animals, arm and leg restraints, a hood, mouthguard and a Secret Service Agent asking for a selfie. This was not your average invitation to meet with the President. But then Orphan X is not your average guest. The last survivor of the off-the-books programme that raised and trained him, Evan Smoak was sent around the world to do his government’s dirty work. Until he escaped. Now once again in need of his particular skill-set, the President tracks him down and offers him a deal: kill a man she deems too dangerous or be executed himself. Evan must decide whether to accept. He’s spent years trying to atone for his former life. But if by taking on the mission he must betray the very principles he now lives by, what is left?
