Showing White Lies by Jayne Ann Krentz

Petite, thirty-something Clare Lancaster is a gifted psychic and a 'human lie detector.' Over the years she's come to accept that someone with her extraordinary talents is likely to have trouble in the relationship department. And she's even resigned herself to the fact that everyone, to one degree or another, hides behind a façade...
Until recently, Clare had never had much to do with her estranged father, Archer Lancaster, so when he summons her from California, she is reluctant to say the least. But after meeting Jake Salter, Archer's financial consultant, Clare is convinced that things aren't what they seem. Something sparks and sizzles between them - something more than just casual flirtation between a man and a woman.

Caught in a dizzying storm of secrets, lies, and half-truths, Jake and Clare must work together in an investigation that demands every bit of their special gifts - together they must overcome their mutual distrust in order to unravel a web of conspiracy and murder.
