Hector is an excellent psychiatrist. He's very good at treating patients who are ill, but more and more; his patients are people he can't treat. They have no serious problems -- they're simply deeply dissatisfied with their lives. Hector can't do much for these people, and it's beginning to depress him. So when a patient tells him he looks in need of a holiday, Hector decides to set off on a trip around the world to try to find the key to happiness. Along the way, Hector keeps a list of observations about the people he meets and learns a great deal about what true contentment is all about. His journey into the soul is entertaining, empowering and often funny -- as winning in its optimism as it is powerful in its simplicity.

In the void that remains stands his widow, FBI agent Jane Hawk, surrounded by questions destined to go unanswered unless she does what all the grief and fury inside her demand: Find the truth, no matter what.

Jane is determined to give up everything to find out why. And if that means going rogue and becoming America's Most Wanted, then so be it. Those arrayed against her are legion, and devoted to protecting something profoundly important-or terrifying-enough to exterminate any and all in their way. But Jane is as clever as these enemies are cold-blooded, as relentless as they are ruthless. And she is driven by a righteous rage they can never comprehend. Because it is born of love.
