Enemy Agents — Shaun Tennant

After a secret branch of the CIA is compromised by someone leaking dangerous information, young agent Chris Quarrel is brought in to root out the traitor. The job is even harder than it seems, because the only people who could be the mole are also the greatest spies in the world:

A master thief. A nameless assassin. A reformed criminal. An amnesiac. A Cold War spymaster. A woman of action. An American patriot. A suave British legend.

One--or more--is a traitor. However, the only agents capable of hunting such dangerous prey are also the very same suspects on his list. So Quarrel does the only thing he can: he sends the world's most dangerous spies to chase each other down.

May the best spy win.
