Republic Commando: True Colors by Karen Traviss

"As the savage Clone Wars rage unchecked, the Republic's deadliest warriors face the grim truth that the Separatists aren't their only enemy - or even their worst. In the Grand Army's desperate fight to crush the Separatists, the secret special ops missions of its elite clone warriors have never been more critical . . . or more dangerous. A growing menace threatens Republic victory, and the members of Omega Squad make a shocking discovery that shakes their very loyalty. As the lines continue to blur between friend and enemy, citizens-from civilians and sergeants to Jedi and generals-find themselves up against a new foe: the doubt in their own hearts and minds. The truth is a fragile, shifting illusion - and only the approaching inferno will reveal both sides in their true colors."
