Lara Jansen is the world's worst liar. Literally.
Born with an uncanny gift to know when the truth is being spoken, Lara lives a quiet, risk-adverse life as a tailor. But when handsome, mysterious Dafydd ap Caerwyn enters her life and claims—truthfully—to be a prince of Faerie, Lara's world is turned upside-down.
Dafydd has traveled from his world—the Barrow-lands—in search of a 'truthseeker' to help untangle the truth around his brother's murder, a crime which the warring factions in the Seelie court can't solve. Lara, determined to take a few chances with her life, agrees to journey to the Barrow-lands with him, but there, discovers that even her gifts don't necessarily prevent people from lying to her...and that charming, irresistible Dafydd has secrets of his own.
Caught between ancient, bitter rivalries and a burgeoning evil wielding dark power, Lara's own abilities grow uncontrollably, and the Barrow-lands may yet discover that truth is the deadliest magic of all....
