Blindfold - Kevin J. Anderson - Bog

Falsely accused of murder on the colony world of Atlas, Troy Boren trusts the young Truthsayer Kalliana . . . until, impossibly, she convicts him. Kalliana doesn't realize her power is fading, but soon the evidence becomes impossible to ignore. The Truthsayer drug Veritas has been diluted and someone in the colony is selling smuggled telepathy. Justice isn't blind -- it's been blinded!
