Edge of danger

"I always return: for centuries, that had been the Rashid motto. Over the years, their British and Arab ancestries had interwoven to produce a remarkable family of warriors, as much at home under the pitiless desert sun as in the streets of London. But it is to neither of these places that the Rashids now direct their rage. It is to the United States, whose president they hold accountable for a series of attacks against their power and their honor. From opposite ends of the world, hints are picked up by Blake Johnson, head of the clandestine White House operation known as The Basement, and his Irish colleague, Sean Dillon, but hints to what? By whom? Frantically, they work to find the answer - and meanwhile the killers wait. And that is only the beginning."--BOOK JACKET.
