In the escalating galaxy-wide chess game of sabotage and retaliations, Sidious stays one move ahead. Then the trail takes a shocking turn. For Sidious and his minions have set in motion a ruthlessly orchestrated campaign to divide and overwhelm the Jedi forces -- and bring the Republic to its knees.
