The fourth book in the Jack Be Nimble series finds Mercedes, Jack, and their companions in a dead run, after pursuing Alex Raines and his assassins for six days across two continents, past move and countermove, straight through mayhem and murder and chaos on a grand scale. Now, on the near horizon at last, lies Raines' island stronghold, the focal point of all his technology and dark ambition. The forces of good and evil align inexorably around them, and both sides poise for a final confrontation. As Jack struggles with the knowledge that he must send his companions onward without him, against an enemy prepared to meet them with the full might of his technology brought to bear, he learns that Mercedes herself now lies across the sea, a willing captive of Alex Raines at the very moment he triggers the ultimate piece of his plan. The final countdown began one week ago. Today is the seventh day. Who will survive?
