Blindfold

Atlas is a struggling colony on an untamable world, a fragile society held together by the Truthsayers. Parentless, trained from birth as the sole users of Veritas, a telepathy virus that lets them read the souls of the guilty. Truthsayers are Justice-infallible, beyond appeal. But sometimes they are wrong. Falsely accused of murder, Troy Boren trusts the young Truthsayer Kalliana.until, impossibly, she convicts him.
Still shaken from a previous reading, Kalliana doesn't realize her power is fading. But soon the evidence becomes impossible to ignore. The Truthsayers' Veritas has been diluted and someone in the colony is selling smuggled telepathy. Justice isn't blind-it's been blinded. From an immortal's orbital prison to the buried secrets of a regal fortress, Kalliana and Troy seek the conspiracy that threatens to destroy their world from within.
For without truth and justice, Atlas will certainly fall.
