I started reading all of Daniel Silva's books. He's great - they're quick reads and really interesting/entertaining. He writes mostly international spy thrillers and now focuses primarily on his main character - Gabriel Allon, an Israeli Mossad agent. His first novel though, the Unlikely Spy, takes place during World War II and he has two other books that feature an American CIA agent (Michael Osbourne).
So far I've read (click to buy at Amazon):
The Unlikely Spy
The Kill Artist
The Mark of the Assassin
The English Assassin
More to come...
