Gone - Lisa Gardner

For ex-FBI profiler Pierce Quincy, it's the beginning of his worst nightmare: a car abandoned on a desolate stretch of Oregon highway, engine running, purse on the driver's seat. And his estranged wife, Rainie Conner, gone, leaving no clue to her fate.

Did one of the ghosts from her troubled past finally catch up with Rainie?
Or could her disappearance be the result of one of the cases they'd been
working - a particularly vicious double homicide or the possible abuse of a deeply disturbed child Rainie took too close to heart? Together with his FBI agent daughter, Pierce is racing against time, frantically searching for answers to all the questions he's been afraid to ask.

One man knows what happened that night - and he's already contacted the press. He wants money, he wants power, he wants celebrity. As the clock ticks, Pierce plunges headlong into the most desperate hunt of his life, into the shattering search for a killer, a lethal truth, and for the love of his life who may forever be gone.
