Rain on the Dead — Jack Higgins

The past comes back to haunt Sean Dillon and his colleagues, as the New York Times-bestselling master of suspense returns with a knife-edge story of terrorism, revenge, and a very old nemesis.

In the past few years, the killing and capture of many Al-Qaeda leaders has left the terrorist organization wounded -- but by no means dead. And they intend to prove it.

On a dark summer night, two Chechen mercenaries emerge from the waters off Nantucket to kill a high-value target, the former president of the United States, Jake Cazalet. Unfortunately for them, Cazalet has guests with him, including black ops specialist Sean Dillon and his colleague, Afghan war hero Captain Sara Gideon.

The Chechens do not survive the night, but Dillon is curious as to how they even got on the island. What he discovers sends a chill through his bones -- a name from very far back in Dillon's past. If this man is working with the terrorists now, the assassination attempt is only the beginning -- and the next time, the results might be much, much different.
