Liars and Tyrants and People Who Turn Blue — Barbara Paul

A human lie detector sets off in search of a revolution

There are 1,500 hand grenades in Alabama's Styx River, and none of them work. Rebels are attacking UN peacekeeping forces in Burma and Honduras, but just when the battle gets started, they find their guns don't fire. Someone is selling defective weaponry to violent men around the globe, and the United Nations needs to find him. In a world where even the good men are liars, it will take Shelby Kent to see the truth.

Shelby is the world's only human lie detector, a psychic who sees a buzzing red aura around anyone -- including her husband -- who tells a lie. Shelby is happy to use her unique powers for the sake of world peace, but she'll find that unthinkable evil lies behind this strange scheme, and clairvoyance is no protection against a madman with a gun.
