When a health scare puts him in the hospital, Eric Weiner-an agnostic by default-finds himself tangling with an unexpected question, posed to him by a well-meaning nurse. "Have you found your God yet?" The thought of it nags him, and prods him-and ultimately launches him on a far-flung journey to do just that. Weiner, a longtime "spiritual voyeur" and inveterate traveler, realizes that while he has been privy to a wide range of religious practices, he's never seriously considered these concepts in his own life. Face to face with his own mortality, and spurred on by the question of what spiritual principles to impart to his young daughter, he decides to correct this omission, undertaking a worldwide exploration of religions and hoping to come, if he can, to a personal understanding of the divine.
