Aim True, My Brothers by William Brown

Middle East terrorism explodes on American shores as a skilled Hamas commander who has battled Americans in Iraq and Afghanistan seeks revenge for the deaths of his brothers by taking his private war to the heart of America unleashing a firestorm that will take out the President and half the American government. With faint clues to go on, it falls to Eddie Rankin, a maverick FBI agent, an Egyptian spy, and a hard-edged, female Mossad agent to stop him — and the clock is ticking.

From the author of The Undertaker, Amongst My Enemies, Thursday at Noon, and Winner Lose All.
