We Interrupt This Program by Lynda Lyons

In a future fully integrated by androids, there's more need than ever for the highly successful Controllers to track down and destroy 'droids who no longer consider themselves to be mere machines. The Controllers are a special force whose primary job is to track down androids who have gone renegade. Lt. Valentine Smith of The Controllers is under the tutelage of superior, Amelia Roberts. This time it's personal for Valentine as a bomb meant for Amelia is planted in the Director's private apartment. But it's still business as usual as Valentine is sent to assure an important interspecies meeting goes well. But, why is the head of The Controllers, Amelia Roberts so standoffish with everyone except for her second in command, Valentine? Is it aloofness? Shyness? Or does she have a secret?
